OpenCubes file formats

[JATothrim]

There are few file formats around. It is however bit unclear what these formats actually are for. This issue is for discussion of the file formats used project wide + their documentation.

• What is the current export file format? I.e. the format all implementations are expected to be able write that contains the polycubes of N=?
• What are the currently used (other) file formats of the implementations?

Rust and python versions seem to implement an format that follows https://github.com/mikepound/opencubes/pull/17#issue-1809988894 so I think this is the export file format.
