87x2262 -> 1131x174
This makes the file smaller and also makes the texture fit
on devices with 2048x2048 max texture size (Fixes#5403).
`button.png` updated with:
convert -crop 87x174 button.png +append out.png
optipng -o9 out.png
mv out.png button.png
libmpq is a much simpler alternative to StormLib for reading MPQ archives.
We use our own fork of libmpq: https://github.com/diasurgical/libmpq
Impact:
* DevilutionX is now a lot more portable. Unlike StormLib, libmpq only
needs platform-specific code for Windows.
* Locks around file access **removed** (instead we duplicate the file descriptor for streamed audio only).
* RAM usage is **300 KiB** lower than StormLib.
* Stripped release linux_x86_64 binary is **32 KiB** smaller.
* Amiga build now hangs instead of crashing.
