Need a common Image LumpClass base type

[snake-biscuits]

We need a solid baseclass for bsp lumps containing image data
Sort of a SpecialLumpClass, but multiple instances per-lump
This could be used for indexing, since some lumps have indices into arrays of raw texels
e.g. titanfall.LIGHTMAP_DATA_SKY / quake.MipTextures

BspLump.from_count could be a useful base
Translating a full batch of pixels is a lot of work after all

Pillow would be best for visualisation imo.
Image[x][y] indexing would also be nice

LumpClasses

• id_software.quake3.Lightmap
• id_software.quake.MipTexture
• infinity_ward.call_of_duty.Lightmap
• wild_tangent.genesis3d.Palette
