The files are way to big they should probably live in STIX-CONF or similar it a bug they pre-commit didn't find this max files size ~1054kb

I guess we need some code to read in the drm and return an nice object for moment could just be the matrix and the two axis (photon and count) as quantities

[samaloney]

We just redefined the energy grid used to create the DRM in IDL

[DanRyanIrish]

For that reason, I think we need to allow users to provide their own DRM, rather than only being able to use the DRM that happened to be attached to a specific version of STIXpy
