KStars fits display

[Hy Murveit]

Mark,

The stretching scheme is based on the spec in section 8.5.6 from this
PixInsight doc:
https://pixinsight.com/doc/docs/XISF-1.0-spec/XISF-1.0-spec.html
See
https://invent.kde.org/education/kstars/-/blob/master/kstars/fitsviewer/stretch.cpp
Not sure what to say about the FITS header.
