Also check the N flag (i.e. set it to zero)

We should check only the first byte for zero
...
We need to accept values for result that are greater than a byte so that
we can determine if carry is set, but this causes an issue when an app
uses addition to force an overflow that would set the zero bit. Masking
result for only the LSB fixes that problem.

Several changes to phase and writes
...
1. The phaser algorithm was reworked, and it should be more accurate in
choosing when to step forward or backward.
2. Writes should be committed when the latch has bit 7 high. This hasn't
actually been a problem yet, since other things are broken! But we might
as well fix it now that we've seen it.

The same track/sector method works for all images

Particularly so as the data segment is now the 6-and-2 encoded form,
which we either encode from DOS 3.3/ProDOS, or use literally from NIB
files.
