Specify units when creating ScopeSIM dictionaries

No units are specified when interacting with ScopeSIM. E.g. this is the dictionary for the DetectorArray:

{'alias': 'DET',
   'class': 'DetectorArray',
   'description': 'A detector array.',
   'effects': [{'class': 'DetectorList',
                'description': 'A single Detector.',
                'kwargs': {'array_dict': OrderedDict([('id', ['']),
                                                      ('angle', [0.0]),
                                                      ('gain', [1.0]),
                                                      ('pixsize', [0.015]),
                                                      ('x_cen', [0.0]),
                                                      ('y_cen', [0.0]),
                                                      ('xhw', [0.24]),
                                                      ('yhw', [0.24]),
                                                      ('filename', ['']),
                                                      ('globalname', [''])])},
                'name': 'detector_array_list'},
               {'class': 'DarkCurrent',
                'description': 'Dark Current.',
                'kwargs': {'value': 10000.0},
                'name': 'dark_current'},
               {'class': 'ShotNoise',
                'description': 'Poisson Noise.',
                'kwargs': {'state': True},
                'name': 'shot_noise'},
               {'class': 'SummedExposure',
                'description': 'Summing up sky signal for all DITs and NDITs.',
                'kwargs': {'state': 0},
                'name': 'exposure_action'}

Units are necessary, see https://gitlab.astro-wise.org/micado/micadowise/-/jobs/20146 and https://github.com/astronomyk/ScopeSim/pull/37 The units are already defined in the DIDs, so should be easy.
