Sector size is now reported, and CRC failures are merely indicated, not cause for a sector to be thrown away.

Broadened CPC data disk analysis to spot when there is only one implicitly-runnable file, rather than only one without suffix.

Expands the [M]FM encoder to respect some new Sector flags: it will now wilfully make CRC errors, omit data, include data that is different than the ID's declared length, write deleted data, and can be commanded as to header/data gaps and what should be within them. All based around expanding towards the needs for reproduction of the CPC's .DSK file format.

Fixed test for termination of a key sequence; the previous error will have seen this reduce all multi-key sequences to just the one, and expand single-key sequences to "probably" two, posting an out-of-bounds code to the machine at completion.

Started working on a CPC-oriented analyser; for now I just want to be able to make a good guess at the appropriate file to load from a disk. As it turns out, the CPC simply adopts the CP/M format, so a generic parser is appropriate. This is its beginning.

Ensured counter-intuitive CRTC writes get through, taking the opportunity to correct my handling of port IO in general: selecting multiple devices for input results in a logical AND (i.e. open collector mode), and both the CRTC and gate array will receive data from 'input's if applicable.
