Add brute force byte guessing to repair a bad sector

[infobrand]

Hello,

First of all, thank you for this wonderful software.

A nice feature would be to add the possibility to try every byte combination possible to recover a dead MFM sector and make it check against the crc value.

It would be useful in that context to be able to select the few wrong bytes of the bad track and be able to check automatically every byte combination on the selection and review the combinations matching the CRC value.

Best regards and thank you for your time.
