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 (?)

It turns out that 5-and-3 disks have a different header prologue.

Fixed: the sector number also goes into sector bodies.
...
Also the checksum is written in the other order, and the final byte of data isn't output.

This is to remove another pain point, in preparation for the work immediately forthcoming but also work as-yet unknown.

Introduces the Disk II as a unique media target platform.
...
As it makes a little more sense to analyse Apple GCR images to determine target platform than it does to have the potential platforms vote over them.
Also starts on the parser that'll be necessary for making a decision.
