Cyphgirl d5fd01bb28 Extract pika saver assets from baserom
All five are OBJ tile data (destinations 0x06010480, 0x06010600 and
0x06015800 are all in OBJ VRAM), and all five are banks of 0x180 frames
drawn as SPRITE_SIZE_32x16 over SPRITE_SIZE_32x8 per
gPikachuKickbackSpriteSet / gPichuKickbackSpriteSet, so each frame is a
4x3 tile rectangle and they convert with -mwidth 4 -mheight 3 -oam.
ROM still matches (make compare).

  gPikaSaverTilesGfx             3 frames
  gDxModePikachuObjTiles         6 frames
  gPikachuSaverTilesGfx          6 frames
  gPikaSaverFullCoverageGfx     24 frames
  gPikaSaverPartialCoverageGfx  24 frames

The first three are one contiguous 15 frame bank: the index expression
gPikaSaverTilesGfx + pikaSaverTileIndex * 0x180 reaches index 9, which
is 0xD80 and lands exactly on gPikachuSaverTilesGfx, so reads run past
the first symbol into the two that follow. The symbol boundaries are
noted in a comment rather than changed.

The coverage pair is declared 0x2420 but only 0x2400 is copied; the
trailing 0x20 is a blank tile and becomes .space 0x20.

The 4x3 shape was not assumed for the coverage pair. At a plain tile
width its sprites are visibly fragmented; as 24 4x3 frames each one
resolves into a single coherent sprite, and the round trip is exact.

PNGs are greyscale, matching pika_spinner.png, the neighbouring pika
asset that uses the same OBJ palette bank (3).
