Check for and fix irregularities in the satbang and satbias restart files
when compared to information in the satinfo.rc and tlapmean.rc files.
satbang and satbias restarts
----------------------------
* Remove all records where the instrument channel is not listed in the
satinfo.rc file.
* Add a new record with coeffs equal zero for each instrument channel
found in the satinfo.rc file but not in the restart file.
* Sort records according to sortflag, if not equal "default"
satbang only
------------
* If the tlapmean value is zero, then replace it with the value from
tlapmean.rc, if one is found there.
* Make a note of the instrument channels with tlapmean equal zero, and
there is no value in tlapmean.rc to replace it.
* Make a note of the instrument channels with a non-zero tlapmean that
disagrees with the value in tlapmean.rc (but do not replace).
