WIP Et tu working-ish

* Sfall-like sound system

(I would like a better name for this system, but the opcodes themselves are called `play|stop_sfall_sound` and I can't think of a better name)

This is a sound management system very similar to Sfall's.  With a few differences:
* No support for new sound formats yet.  Support for at least ogg+wav will come next
* Does support reading from .dat files, hence playing any sound effect in the base game
* Support mode=3 for speech volume.  This exists in Sfall but is ignored when called from the opcode.

Also, change GaplessMusic to use this system to play the "wind2" loading sound.  This restores the "vanilla" feel map transitions, so I think it's reasonable to make GaplessMusic=1 the default.  I can't imagine someone wanting to change it to 0 unless they are ultra purists

 Use `--lower` with `extract` when you want every extracted file and directory name forced to lowercase.
 For example:
 
-`fallout2-dat master.dat extract --lower /tmp/fallout2-dat-lower data\\*`
+`ce-dat-tool master.dat extract --lower /tmp/ce-dat-tool-lower data\\*`

+There is also a small FRM conversion tool in this repo for exporting Fallout `.frm` art to `.png`.
+
+From the repo root, build it with your normal CMake workflow, targeting `ce-frm2png`:
+
+`cmake --build out/build/<preset-name> --target ce-frm2png`
+
+The executable is written to your selected build directory, so the exact path will vary by preset and configuration.
+
+Basic usage:
+
+1. `./<BUILD_DIR>/ce-frm2png <input.frm> [output.png]`
+2. `./<BUILD_DIR>/ce-frm2png <input.frm> [output.png] --palette <path-to-color.pal>`
+3. `./<BUILD_DIR>/ce-frm2png <input.frm> [output.png] --frame <index> --direction <index>`
+4. `./<BUILD_DIR>/ce-frm2png - [output.png|-] --palette <path-to-color.pal>`
+
+`-` can be used to take input from stdin (e.g. from `ce-dat-tool cat` or write to stdout).
+
+If `--palette` isn't specified, it will pick up `color.pal` in the .frm's directory or cwd.
+
+Notes:
+
+- The tool expects a raw `color.pal` file. It does not read palettes directly from `master.dat`, so extract `color.pal` first if needed.
+- A typical extraction flow is: `ce-dat-tool master.dat extract --lower . 'color.pal'`
+- By default palette index `0` becomes transparent in the output PNG. Pass `--opaque` to keep it opaque.
+- The current implementation writes RGBA PNGs. It does not preserve the original Fallout palette indices as a palette-indexed PNG.

 Popular Fallout 2 total conversion mods are partially supported. Original versions of Nevada and Sonora (that do not rely on extended features provided by Sfall) work.

 * High resolution support
+* Expanded 2-column inventory
+* Expanded 4-row barter screen
+* Expanded AP bar
 * Increased pathfinding nodes 5x for more accurate pathfinding
 * Ctrl-click to quickly move items when bartering, looting, or stealing
 * _a_ to select "all" when selecting item quantity
 * _a_ to `Take All` when looting
 * When bartering, caps default to the right amount to balance the trade (if possible)
