option for a stellar mask

A stellar mask seems now feasible, since template masking is now elaborated.
The badT flag is propagated (flagbroad).

For now one can modify the QMAP extension in the serval template fits files, which is then loaded in

serval/src/read_spec.py

Line 294 in b7c7b56

return 1*hdu['WAVE'].data, hdu['SPEC'].data, (hdu['QMAP'].data if 'QMAP' in hdu else None), hdu[0].header

serval/src/serval.py

Line 1407 in b7c7b56

ww, ff, qq, head = read_template(tpl+(os.sep+os.path.basename(tpl.rstrip(os.sep))+'.fits' if os.path.isdir(tpl) else ''))

And finally masked in:

serval/src/serval.py

Line 207 in b7c7b56

self.msk_fast = interp(self.wk, 1.*(BK>0))

More convenient would be an -mskstar option. Ups, there is already a -mskspec option; but it does nothing yet

serval/src/serval.py

Line 2604 in b7c7b56

argopt('-mskspec', help='Ascii 0-1 spectrum.'+default, default='')

The mask may need a shift to the frame of the template (RVabs, maybe using the keyword HIERARCH SERVAL TARG RV.

The mask could by applied to the bk (bad knot) map outside or inside the Tpl instance creation
