FITS: Add missing `application/fits` and legacy globs
Make `image/fits` an alias, matching its designation of a subset of
the FITS standard, as per https://datatracker.ietf.org/doc/html/rfc4047#section-5 -
"The general nature of the full FITS standard requires the use of the
media type "application/fits". Nevertheless, the principal intent
for a great many FITS files is to convey a single data array in the
PHDU, and such arrays are very often 2-dimensional images. Several
common image viewing applications already display single-HDU FITS
files, and the prototypes for virtual observatory projects specify
that data provided by web services be conveyed by the data array in
the PHDU. These uses justify the registration of a second media
type, namely "image/fits", for files which use the subset of the
standard described by the original FITS standard paper."
The existing alias `image/x-fits` was common before the standardization
of `application/fits` and `image/fits`, so it should stay.
Current standards and historical contexts can be found here:
- https://fits.gsfc.nasa.gov/fits_standard.html
- https://listmgr.nrao.edu/pipermail/fitsmime/2002-December/thread.html
- https://www.ucolick.org/~sla/fits/mime/comments.html
Add missing eight-dot-three-style `*.fit` and `*.fts` globs for legacy files,
matching the list supported by `libvips`, i.e.,
https://github.com/libvips/libvips/blob/757d03100566368e5d06c7355e73c1215dd34968/libvips/foreign/fits.c#L132
And as discussed in the FITS standard definition (`fits_standard40aa-le.pdf`) -
"In the absence of other information it is reasonably safe to
presume that a file name ending in ‘.fits’ is intended to be
a FITS file. Nevertheless, there are other commonly used ex-
tensions; e.g., ‘.fit’, ‘.fts’, and many others not suitable for
listing in a media type registration."
