Started implementing write sector on the 1770, immediately deciding it would be useful to have a callback for end-of-queued-data-written from disk controller. So had a go at implementing that, naively. More investigation required.

Added enough stuff that SSDs attached to a 1770 will now reach the entry point for writing.

Actually, at least index holes will still be receivable while writing, so this wasn't entirely correct. Probably best to leave it in.

Still by manual inspection: the time for the next event should be provisional until proven acceptable, allowing a proper measurement of time until exiting the period to be taken; also fixed the accumulated period error when seeking back onto the underlying track.
