Add Data Interface Control Dictionaries for METIS?

[hugobuddel]

Attached are the DICD (Data Interface Control Dictionaries) that I wrote for MICADO, micadodicd.zip. The conversion to yaml is included as well.

The DICD files are ASCII files named like ESO-ELT-DIC.MICADO_DET, with entries like

Parameter Name:    DET ANGLE
Class:             header
Context:           Detector
Type:              double
Value Format:      %.3f
Unit:              degree
Comment Format:    Angle of detector
Default:           0.0
Description:       Angle of detector

For MICADO I used those to define what all keywords mean. Where they were used was defined in the data model (that we don't have for METIS).

I propose we just use these DICD files for now, and put them in the IRDB. Maybe in the METIS/dicd directory? Then in the METIS/headers directory we put where these keywords are used.

I'm not sure about the future of these DICD files. To some extent they are being replaced by a new format that I do not have access to anymore. But much of the information was missing in this new format.
