Make use of extra geom for report figures

Description

In this PR, we introduce the usage of EXtra-geom for rendering processed modules of all detectors, instead of some mystery code.

Yes, I am a savage, and yes, I am using the geometry from the tests folder 👍

How Has This Been Tested?

This can be tested so:

import pytest
from cal_tools.plotting import show_processed_modules
mnames = ['Q1M1']

for detector in ('DSSC', 'AGIPD1M2', 'AGIPD500K', 'LPD'):
    show_processed_modules(detector, mnames=mnames, constants={}, mode='processed')

with pytest.raises(ValueError) as err:
    show_processed_modules('LDP', mnames=mnames, constants={}, mode='processed')
assert err.value.args[1] == 'LDP'
