Cauldron2D.GameMaker.Chunks (Cauldron2D.GameMaker v0.2.1)

The chunks of a GameMaker data file: a FORM holding four-letter named chunks, each a length and its bytes.

{:ok, chunks} = Cauldron2D.GameMaker.Chunks.index(bytes)
{offset, size} = chunks["SPRT"]

Offsets are absolute and point past the chunk's eight-byte header.
