Verification of No-Flux Areas is unreliable

[keirf]

Example: Writing T0.0 of Theme Park Mystery for Atari ST (SPS IPF #3211).

This track contains a 2ms NFA. On verification the read-back track will be converted to bitcells, and the number of 0s may not match the source image due to speed variations and lack of self-clocking flux transitions.

This is possibly relevant only when writing IPF image, at least currently. I don't believe any EDSK images contain an NFA.
