DAXA v0.2.0 - Now with updatable archives!

Summary

Some small bug fixes which impacted eROSITA missions, and an unintentional incorrect unit on the definition of the Swift BAT nominal FoV. The major change is that archives are now easily updatable with new observations (if they become available). They can simply be re-loaded in the usual DAXA way, and then the 'update()' method can be called - this will reapply the stored filtering operations used for each mission instance (with the same configuration, in the same order) and then run any processing steps that were applied, in the same order and with the same configuration.

What's Changed
