Description
GE stores data as view, segment, tangential coordinate, axial coordinate. ProjDataFromStream currently doesn't support this.
@nikefth's listmode PR https://github.com/UCL/STIR/pull/108 introduced a function get_offsets_bin. All the other get_offset_ functions should be rewritten in terms of that one, such that we have a single point of modification. The reading/writing functions then "just" need to check if the data is contiguous or not, and if not, resort to a lot of seek/IO stuff.

Research direction
Start in ProjDataFromStream and trace get_offsets_bin alongside the other get_offset_ functions, using the listmode PR #108 for context. Check how the reading and writing functions handle contiguous data, then verify support for the view, segment, tangential-coordinate, and axial-coordinate order described in the issue, including the non-contiguous case.
