System for drawing organs with overlays. These overlays are drawn directly on the bodypart, attached to a person or not Works in tandem with the /datum/sprite_accessory datum to generate sprites Unlike normal organs, we're actually inside a persons limbs at all times

Vars
all_layers	Convert the bitflag define into the actual layer define
cache_key	Key of the icon states of all the sprite_datums for easy caching
dna_block	With what DNA block do we mutate in mutate_feature() ? For genetics
layers	Sometimes we need multiple layers, for like the back, middle and front of the person
organ_flags	Unremovable is until the features are completely finished
ownerlimb	Reference to the limb we're inside of
preference	Defines what kind of 'organ' we're looking at. Sprites have names like 'm_firemoth_mothwings'. 'mothwings' would then be preference
sprite_datum	Sprite datum we use to draw on the bodypart
Procs
Initialize	mob_sprite is optional if you havent set sprite_datums for the object, and is used mostly to generate sprite_datums from a persons DNA For _mob_sprite we make a distinction between "Round Snout" and "round". Round Snout is the name of the sprite datum, while "round" would be part of the sprite I'm sorry
bitflag_to_layer	Converts a bitflag to the right layer. I'd love to make this a static index list, but byond made an attempt on my life when i did
can_draw_on_bodypart	Check whether we can draw the overlays. You generally don't want lizard snouts to draw over an EVA suit
generate_icon_cache	Generate a unique key based on our sprites. So that if we've aleady drawn these sprites, they can be found in the cache and wont have to be drawn again (blessing and curse)
get_global_feature_list	Return a dumb glob list for this specific feature (called from parse_sprite)
get_overlays	Add the overlays we need to draw on a person. Called from _bodyparts.dm
get_sprite_datum	Because all the preferences have names like "Beautiful Sharp Snout" we need to get the sprite datum with the actual important info
mutant_bodyparts_layertext	This exists so sprite accessories can still be per-layer without having to include that layer's number in their sprite name, which causes issues when those numbers change.
mutate_feature	Update our features after something changed our appearance

Return a dumb glob list for this specific feature (called from parse_sprite)
