Attempt to fix DREAMS

[hugobuddel]

This fork does produce an image on the center two detectors:

I can't see from this thumbnail whether the image makes sense. But at least it is an image.

The biggest problem for me to do this properly is that I do not have the J-filter data, that is, I do not have J.dat. Therefore I used I.dat from LFOA. @Astrogirlanajli could you include your J.dat in the filters directory?

So perhaps it is possible to ignore most filter/spectrum related changes. However, the curve in TER_atmosphere.dat looks suspicious, since the wavelength claims to be in nanometer, but it ranges from 0.9 to 1.05, while the J band should be around 1200 nanometer. I simply added a (fake) data point at 1100 nanometer (to cover the I-band that I used).

Other changes:

• Indenting of the rescaling parameters in DREAMS.yaml
• Renaming mage_plane_id to image_plane_id in DREAMS_InGaAs.yaml
• Converting the dark current to float in DREAMS_InGaAs.yaml (I'd say that this is a bug in ScopeSim)
• Giving M1 some surface area (it was a 0-width ring), but this seems to have no effect
• Adding an emission_unit to TER_atmosphere.dat
• Adding action transmission to TER_atmosphere.dat (I think transmission is the default, so this should not matter)
• Adding three dashes (---) to default.yaml to separate the two parts of the yaml file
• Plot all 6 detectors

@Astrogirlanajli could you verify that you get some result using this branch?

Could you please put the file J.dat in the repository? In the directory filters. I do not have J.dat, so I cannot run the code with the J filter specified. That's why I used I.
