kris c797852324 - Stop masking out unchanged bytes explicitly and compare the full ...

source vs target frame.  This allows us to accumulate runs across
unchanged bytes, if they happen to be the same content value.

- introduce an allowable bit error when building runs, i.e. trade
  some slight imprecision for much more efficient decoding.  This gives
  a slight (~2%) reduction in similarity on my test frames at 140 pixels
  but improves the 280 pixel similarity significantly (~7%)

- so make 280 pixels the default for now

- once the run is complete, compute the median value of each bit in
  the run and use that as content byte.  I also tried mean which had
  exactly the same output

- runs will sometimes now span the (0x7x) screen holes so for now just
  ignore invalid addresses in _write
