DAXA XMM processing might not be generating exposure maps correctly all the time #303

This is evident in a one LoVoCCS-selected observation (0653050201), where the PN 0.5-2.0 keV exposure map is just empty, but the 2.0-10.0 keV seems just fine.

There are also some failed images that lack the required WCS.

Okay this is happening for images too

As I'm using the XGA functions to do this, there is no proper logging - I should either re-implement the image and exposure map generation functions in DAXA, or implement permanent logging in XGA (https://github.com/DavidT3/XGA/issues/1233) and grab those files.

Maybe I should do both honestly
