Default filter for MICADO SPEC_3000x16

[teutoburg]

Currently, MICADO/default.yaml sets the filter for the SPEC_3000x16 mode to Spec_HK. This is in conflict with Ric's PDF, which in Table 15 states that this mode (called "short slit" there) is only combined with the Spec_IJ filter. For the other two modes, the current setting is correct.

In addition, I'm wondering whether there should be separate modes for the Spec_IJ filter in SPEC_3000x48 mode and the J filter in SPEC_15000x20 mode? Or do we keep the as the user's duty? This might be combined with a proposed new FilterWheelList and a list of "allowed" filter combinations...

For the first issue, simply change the default to Spec_IJ. I don't think it's necessary to disallow Spec_HK within Scopesim/irdb.
For the second issue, I'm in favour of reducing the number of modes rather than augmenting it even further. Choosing a slit and a filter are standard configuration tasks for any observer, and some instrument knowledge can certainly be expected from serious Scopesim users. Ric's document is as good as any to provide that knowledge and should feature prominently in the irdb documentation.
