LagoLunatic a1ea2919f8 Reimplement function data value tooltips, function data value diffing, and data relocation diffing (#166)
* Show data literal values on instruction hover

Reimplements #108

* Show reloc diffs in func view when data's content differs

Reimplements #153

* Data diff view: Show relocs on hover and in context menu

This reimplements #154

Note that colorizing the text depending on the kind of diff has still not been reimplemented yet

* Fix up some comments

LagoLunatic a4fdb61f04 Implement diffing relocations within data sections (#154)
* Data view: Show data bytes with differing relocations as a diff

* Data view: Show differing relocations on hover

* Symbol list view: Adjust symbol/section match %s when relocations differ

* Improve data reloc diffing logic

* Don't make reloc diffs cause bytes to show as red or green

* Properly detect byte size of each relocation

* Data view: Add context menu for copying relocation target symbols

* Also show already-matching relocations on hover/right click

* Change font color for nonmatching relocs on hover

Luke Street 21f8f2407c Relax symbol comparison logic
The Ghidra delinker plugin emits functions with type STT_OBJECT,
rather than STT_FUNC. The current logic was preventing these from
being compared based on their symbol type. Relax this condition
for now.

Anghelo Carvajal 5ef3416457 Improve dependency gating on objdiff-core (#126)
* Reduce dependencies for no features

* Add missing deps to every feature

* Add missing `dep:`s

* Gate even more deps behind features

Removes dependency on tsify-next / wasm-bindgen unless
compiling with the wasm feature by using `#[cfg_attr]`

* Fix wasm

Luke Street 676488433f Fix resolving symbols for section-relative relocations
Also fixes MIPS `j` handling when jumping within the function.

Reworks `ObjReloc` struct to be a little more sensible.

Luke Street 741d93e211 Add symbol mapping feature (#118)
This allows users to "map" (or "link") symbols with different names so that they can be compared without having to update either the target or base objects. Symbol mappings are persisted in objdiff.json, so generators will need to ensure that they're preserved when updating. (Example: https://github.com/encounter/dtk-template/commit/d1334bb79e71af1a7b3b090bffda4adc483f722c)

Luke Street e1ccee1e73 Improve data section diffing more
This re-implements the older algorithm
used for data and BSS section match
percentages. We perform both and
choose the highest match percent
between the two options.
