The problem of pulling a version of Saturn header

[fuzz6001]

Sometimes illegal version formats exist.
In this case, the wrong serial number is reported and no version is reported.

e.g.
http://redump.org/disc/3238/

SS [dump (Track 1).bin]:
  build date: 1996-02-20
  serial: GS-9055V1
  regions: Asia NTSC, Japan
  header:
0000 : 53 45 47 41 20 53 45 47  41 53 41 54 55 52 4E 20   SEGA SEGASATURN 
0010 : 53 45 47 41 20 45 4E 54  45 52 50 52 49 53 45 53   SEGA ENTERPRISES
0020 : 47 53 2D 39 30 35 35 20  56 31 2E 30 35 20 20 20   GS-9055 V1.05   
0030 : 31 39 39 36 30 32 32 30  43 44 2D 31 2F 31 20 20   19960220CD-1/1  

another illegal format
http://redump.org/disc/17418/

0020 : 54 2D 34 33 30 35 47 20  56 31 2E 20 20 30 30 32   T-4305G V1.  002

I'm not sure what the ideal output from Redumper should be here.
These weird discs allocate 8 bytes to the serial and 8 bytes to the version, rather than 10 and 6.
If there are a few discs that use 8/8 instead of 10/6 then redumper could check 8/8 if an invalid version is returned initially.

At least these are rare and when adding to redump we would notice this in the logs.

This can be handled correctly. You probably saw my MCD code. How it was implemented - I extracted those headers from all available roms to see all the corner cases and defined a permissive struct for all combinations.
Sega is known to not be very compliant in their headers. I think internally they treat it just as a long string.
