The PR incorporates some changes made during tests done for the DAP overview paper:
Keywords for emission-line moment calculations and model fitting and spectral-index fitting can be None, meaning that the DAP will only fit the stellar kinematics, but not fault when producing the MAPS and model cube output files.
Fixed a bug when handling the templates when the stellar kinematics mode that uses a single global template is selected.
