* Apple-II: per-disk, per-sector DSK writeback
The previous a2_writeNib2Dsk relied on module-static globals (track buffer,
current_track, bytes_accumulated) so two mounted .dsk images corrupted each
other, and used the byte counter as a buffer high-water mark which lost
sectors on any non-sequential LBA pattern. Checksums were also decoded but
discarded, so false sectors fabricated from gap bytes could be written.
Replace with a per-disk write state array (4 slots, matching the SD
dispatcher), and flush sectors one at a time as soon as the parser finds a
checksum-valid match anywhere in the per-track buffer. A 16-bit bitmap
suppresses redundant FileWrites when subsequent LBAs re-expose the same
sector. parse_nib_sector now verifies the address-field and data-field
checksums; the read path, encoding tables, and interleave tables are
untouched.
