[v2][_commonspeckle] what about functions for SMI?

Do we need to keep, incorporate into CHX function, or create a generic scattering

There is WAXS stuff too, but treated basically the same as SAXS?

Start by comparing the matching definitions in DataGonio.py, Stitching.py, and XPCS_GiSAXS.py, especially set_angles, stitch_WAXS_in_Qspace, stitch_WAXS_in_Qspace_CHX, and get_alphaf_thetaf. Review their SMI, WAXS, and SAXS references first; done requires an agreed decision on retaining, incorporating, or generalizing the functions.
