Treading water some more, ensured the DFS and ADFS ROMs get to the Electron. It now even inserts the DFS ROM if it has a DFS disk image. Might need to make it a sideways RAM though? Regardless, the next job surely — surely! — has to be to stop avoiding the 1770?

Tweaked disk side density, added call-outs to a WD1770 if the Electron had one (albeit without run_for_cycles yet as I need to figure out the clock rate), added a shell of the basic functions of the WD1770. No implementation yet.

DFS disks are now delivered right up to the emulator's front door. So everything's in place to get started on that WD1770 nonsense.

There's no cache and no CRC checking yet, but this is probably a rough outline of an FM parser.

Workaround for a weird bug that suddenly appears to manifest: gzgetc is returning the file name, not bytes from the file. Seems to be related to improper initialisation of the next field within the gzFile header. I can't immediately see where ZLib intends to do that so it's a bit mysterious. But the larger-than-8 readers could probably save time by reading in blocks anyway.
