This PR implements a submode using the MICADO calibration assembly. ELT and Armazones atmosphere are not included in this mode. The PSF is only instrumental, and the absorption spectrum of the air in the path through the relay optics is taken into account. The mode stands in for the AO modes and can be combined with all the instrument modes, e.g.

cmd = sim.UserCommands(use_instrument="MICADO", set_modes=["CALIB", "IMG_1.5mas"])

The mode should be used with a Source (to be defined).

Closes #363

Thanks - this looks great! We should remember to confirm the default PSF size with JU.
Regarding the relay optics. We need to add two surfaces specific to the MCA: the deployable mirror and the "filter" that represents the air column. Also, later the MCA would be used with MORFEO, so then we should replace the RO and AO mode definitions used for calibration appropriately.

The air transmission in the relay optics looks like this (in effect air_transmission, available in steps of 5% in relative humidity, only subset plotted here):
