Howard M. Harte 313d71b73e sim_imd: Properly calculate IMD sectsize. ...

The ImageDisk sectsize field was incorrectly set to the number of
bytes in the sector, when it should be an index as follows:

00 =  128 bytes/sector
01 =  256 bytes/sector
02 =  512 bytes/sector
03 = 1024 bytes/sector
04 = 2048 bytes/sector
05 = 4096 bytes/sector
06 = 8192 bytes/sector

Tested disk formatting on MS-DOS 1.25, Cromemco CP/M 2.2,
Cromemco CDOS, OASIS 5.6.
