We want to be able to use unpacked MPQs on low-end platforms
(PS2/rg99/etc).
This is tricky on case-sensitive filesystems. Avoids case issues by
lowercasing all paths in the code (then we'll just need lowercased
listfiles).
The format is almost identical to CL2, except it uses the frame header
to store frame width and height instead of 5 32-line offsets.
This means we always have access to frame dimensions, so we can use it
as an on-disk format for our graphics as well.
Additionally, we may be able to optimize the rendering even more
in the future now that we have guaranteed knowledge of frame dimensions.
Convert CEL files to CL2 at load time. CL2 format is more efficient and is about as fast to render.

Memory:
* Peak memory (while loading): -300 KiB
* Memory in-game (dLvl5): -700 KiB
* RG99 binary size: -15 KiB (1333096 -> 1317192)
Performance on rg99:
* On average, -1 FPS in town.
* Same FPS in dungeon (20 FPS on dLvl 1).
Rather than using the Windows-like `MAX_PATH`, what we really want is 2
things:
1. Maximum path of a file in an MPQ. This is now `MaxMpqPathSize`.
2. Max size for the known monster paths. This is now 64 for sounds and
TRNs, which is more than enough (picked arbitrarily).
Adds simple string / integer concatenation functions.
Many of the uses of `fmt::format` are simply concatenation
of a few strings and integers.
`StrCat` is an easier-to-read alternative to such uses of `fmt`.
1. Store all key data and all values data as 2 char arrays.
2. Change map keys to char pointers.
3. Change map values to offsets into the values array.
Example savings for Russian: 460 KiB -> 374.2 KiB (-85.8 KiB)
* Map: 68.5 KiB (with `string_view` keys it would be 101.5 KiB)
* Keys array: 108.7 KiB
* Values array: 197.0 KiB
* Non-int versions of `Point` and `Displacement`
This will allow us to make some structs, such as `ActorPosition`, much
smaller.
* ActorPosition: Use smaller types
`Monsters`: 56K -> 46K
* player.cpp: Reduce size of `DirectionSettings`
* CrawlTable: Displacement -> DisplacementOf<int8_t>
* CrawlTable: vector<vector> -> array<vector>
Also only allocate one vector during construction instead of two.
A bit less indirection.
* Monster#enemyPosition: Point -> WorldTilePosition
sizeof(Monster): 240 -> 232
* Monster: Further optimize field layout and sizes
sizeof(Monster): 232 -> 208
`Monsters` is down to 40,000 bytes
* DMonsterStr: _mx/_my -> position
* Add MakeRectangle helper to convert from SDL_Rect
* Add Rectangle::inset method for shrinking a rectangle
Turns out some of the other use cases I though this could apply to were actually doing something based on a fixed region
* Simplify initialisation of settings menu rects
* Use explicit typecasts to force signed char comparisons
Avoids warnings about tautological comparisons (either the >= 0 comparison for ARM/PowerPC or the <= 127 comparison for x86*)
* Remove unused function
* Use appropriate types for size constants in control.cpp
* Declare constexpr value for iterating over the cells in a stash grid
* Use appropriate type for UIRectangle dimensions
