Map files will always have either a PNTS or EPNT chunk, depending on what the

Map files will always have either a `PNTS` or `EPNT` chunk, depending on what

the map (and editor) use. `PNTS` are plain and have no more information than

the actual position, while `EPNT` can be loaded directly into memory by the

`iidx` chunk also exists.
