80ece33e3e Document wBattleAnimFlags
`anim_clearsprites` was misnamed, so I renamed it to `anim_keepsprites`,
and documented it in docs/battle_anim_commands.md

7e93916c8a Add more constants for battle anim structs
Any access of the wram arrays for battle anim objects and background
effects use appropriate macros and constants, now.

ee86b36766 wNumActiveBattleAnims → wLastAnimObjectIndex
This variable never decrements, it only increments to give each battle
animation a different, and incremental "index".

4154f191e0 Anotate more of the battle anim subsystem
The X and Y flip flags can be applied through the stack consisting of:
- Object attributes
- Animation frame attributes
- OAM Data
Each of these negate eachother.

Confused yet? The same stack is traversed to obtain the final tile ID,
with an added layer on top for the base GFX offset and the offset for
the dynamically loaded GFX requested by the object!

wBattleAnimDelay is populated with the values passed to `anim_wait`.

c4979d9770 Rename "feet and head follow" commands
The lot of these were rather misnamed, since they're used to replace
part of the player or enemy with objects for several background effects.

41f39211ca Identified another user of wBattleAnimTemp
QueueBattleAnimation loads an object using these wram addresses. Usually
populated by the anim_obj command, but in a couple of cases also
manually.

2746288030 Define ANIM_GFX for PLAYER and ENEMY
These are used where the head or the feet of the player/enemy have to be
moved in an animation, and shouldn't overlap. These aren't actual GFX
and should be loaded with the proper commands, and they're always loaded
at the end of the VRAM area.

Furthermore, I've defined BATTLEANIM_BASE_TILE, which is the tile from
which battle animation graphics may start to load. This value was picked
to make sure at least an entire pokemon pic fits in the area before it,
even though it doesn't seem very used...

eb1e3636bb Use labels instead of constants for HRAM
Use explicit ldh instruction to access HRAM locations, don't rely on optimizing ld
