sat_code

Some TLEs are '3LE's (three-line elements), wherein the name is prefaced by '0 '. We don't want to show the '0 '.

'sat_eph' : added command-line switch to set an arbitrary RA/dec offset. Needed for an unusual case where we had such an offset and wanted ephems to fit it. Not something I expect to get much use.

Sat_ID could be _very_ slow when reading large files with lots of spacecraft or roving observations, such as the ITF. I realized that a small performance observation made it run several times faster on such files. (Not much effect in general, however.)

Sat_ID now has '-fa' (make identifications only to artificial objects) and '-fn' (only natural objects) command line options. Default is to make identifications to both types of objects.
