Avoid off-by-one error in sector decoding.
Specific issue: retaining the 256 bytes up to _and including_ the checksum, rather than excluding.

Liberalises segment parser not necessarily to require a standard epilogue.
It seems that real disks don't always have them; I guess the boot ROM doesn't require one.

Takes some steps towards five-and-three decoding.
Now I 'just' need to figure out how bits are distributed within the decoded sector. The XORing and data checksum seem the same (?)
