The sherpa.astro.io.types module

Useful types for Sherpa Astronomy I/O.

This module should be considered an internal module as its contents is likely to change as types get added to Sherpa and the typing ecosystem in Python matures. These types are primarily for communicating between the front and back ends, as well as providing some structure to FITS-like data structures.
