Dave AllieandGitHub 27035b2b91 Handle 16x16 MCU blocks in JPEG decoding (#120)
## Summary

* Handle 16x16 MCU blocks in JPEG decoding
* We were only correctly handling 8x8 blocks, which means that we did
not correctly support a lot of JPGs leading to an interlacing style on
the images

## Additional Context

* Fixes https://github.com/daveallie/crosspoint-reader/issues/118

Brendan O'LearyandGitHub 9f4f71fabe Add AP mode option for file transfers (#98)
## Summary

* **What is the goal of this PR?** Adds WiFi Access Point (AP) mode
support for File Transfer, allowing the device to create its own WiFi
network that users can connect to directly - useful when no existing
WiFi network is available. And in my experience is faster when the
device is right next to your laptop (but maybe further from your wifi)

* **What changes are included?**
- New `NetworkModeSelectionActivity` - an interstitial screen asking
users to choose between:
- "Join a Network" - connects to an existing WiFi network (existing
behavior)
- "Create Hotspot" - creates a WiFi access point named
"CrossPoint-Reader"
  - Modified `CrossPointWebServerActivity` to:
    - Launch the network mode selection screen before proceeding
- Support starting an Access Point with mDNS (`crosspoint.local`) and
DNS server for captive portal behavior
    - Display appropriate connection info for both modes
- Modified `CrossPointWebServer` to support starting when WiFi is in AP
mode (not just STA connected mode)

## Additional Context

* **AP Mode Details**: The device creates an open WiFi network named
"CrossPoint-Reader". Once connected, users can access the file transfer
page at `http://crosspoint.local/` or `http://192.168.4.1/`
* **DNS Captive Portal**: A DNS server redirects all domain requests to
the device's IP, enabling captive portal behavior on some devices
* **mDNS**: Hostname resolution via `crosspoint.local` is enabled for
both AP and STA modes
* **No breaking changes**: The "Join a Network" option preserves the
existing WiFi connection flow
* **Memory impact**: Minimal - the AP mode uses roughly the same
resources as STA mode

Dave AllieandGitHub 689b539c6b Stream CrossPointWebServer data over JSON APIs (#97)
## Summary

* HTML files are now static, streamed directly to the client without
modification
* For any dynamic values, load via JSON APIs
* For files page, we stream the JSON content as we scan the directory to
avoid holding onto too much data

## Additional details

* We were previously building up a very large string all generated on
the X4 directly, we should be leveraging the browser
* Fixes https://github.com/daveallie/crosspoint-reader/issues/94

Jonas DiemerandGitHub ce37c80c2d Improve power button hold measurement for boot (#95)
Improves the duration for which the power button needs to be held - see
#53.

I left the measurement code for the calibration value in, as it will
likely change if we move the settings to NVS.

## Summary

* Swap from `wasReleased` to `isPressed` when checking power button
duration
  * In practice it makes the power down experience feel a lot snappier
* Remove the unnecessary 1000ms delay when powering off

## Additional Context

* A little discussion in here:

Dave AllieandGitHub 424104f8ff Fix incorrect justification of last line in paragraph (#90)
## Summary

* Fix incorrect justification of last line in paragraph
* `words` is changing size due to the slice, so `isLastLine` would
rarely be right, either removing justification mid-paragraph, or
including it in the last line.

## Additional Context

* Introduced in #73

Dave AllieandGitHub 955c78de64 Book cover sleep screen (#89)
## Summary

* Fix issue with 2-bit bmp rendering
* Add support generate book cover BMP from JPG and use as sleep screen

## Additional Context

* It does not support other image formats beyond JPG at this point
* Something is cooked with my JpegToBmpConverter logic, it generates
weird interlaced looking images for some JPGs

Dave AllieandGitHub 958508eb6b Prevent boot loop if last open epub crashes on load (#87)
## Summary

* Unset openEpubPath on boot and set once epub fully loaded

## Additional Context

* If an epub was crashing when loading, it was possible to get the
device stuck into a loop. There was no way to get back to the home
screen as we'd always load you back into old epub
* Break this loop by clearing the stored value when we boot, still
jumping to the last open epub, but only resetting that value once the
epub has been fully loaded

Dave AllieandGitHub 2a27c6d068 Add JPG image support (#23)
## Summary

- Add basic JPG image support
- Map JPG back to 2-bit BMP output
- Can be used to later render the BMP file from disk or directly pass to
output if wanted
- Give the 3 passes over the data needed to render grayscale content,
putting it on disk is preferred to outputting it multiple times

## Additional Context

- WIP, looking forward to BMP support from
https://github.com/daveallie/crosspoint-reader/pull/16
- Addresses some of #11

Dave AllieandGitHub b73ae7fe74 Paginate book list and avoid out of bounds rendering (#86)
## Summary

* Paginate book list
* Avoid out of bounds rendering of long book titles, truncate with
ellipsis instead

## Additional Context

* Should partially help with
https://github.com/daveallie/crosspoint-reader/issues/75 as it was
previously rendering a lot of content off screen, will need to test with
a large directory

Dave AllieandGitHub f264efdb12 Extract EPUB TOC into temp file before parsing (#85)
## Summary

* Extract EPUB TOC into temp file before parsing
* Streaming ZIP -> XML parser uses up a lot of memory as we're
allocating inflation buffers while also holding a few copies of the
buffer in different forms
* Instead, but streaming the inflated file down to the SD card (like we
do for HTML parsing, we can lower memory usage)

## Additional Context

* This should help with
https://github.com/daveallie/crosspoint-reader/issues/60 and
https://github.com/daveallie/crosspoint-reader/issues/10. It won't
remove those class of issues completely, but will allow for many more
books to be opened.

926c786705 Keep ZipFile open to speed up getting file stats. (#76)
Still a bit raw, but gets the time required to determine the size of
each chapter (for reading progress) down from ~25ms to 0-1ms.

This is done by keeping the zipArchive open (so simple ;)).

Probably we don't need to cache the spine sizes anymore then...
