Use scopesim_templates

scopesim_templates has a micado subpackage now: https://github.com/astronomyk/ScopeSim_Templates/tree/master/scopesim_templates/micado

It should be used in MicadoWISE:

• first add empty_sky to the micado subpackage, and let the dark observe that
• then add a flat_source, e.g. https://github.com/astronomyk/ScopeSim/blob/A_5_liners/docs/source/use_examples/5-liners/source_from_arrays.rst
• then add a star cluster

That should be enough to simulate all standard images.

(Creating instances of these objects is necessary to create header keywords, so might as well simulate them.)
