change the treatment of the strip y coordinates which previously did
not follow the description (nor did it behave like the binary decoder
on files with absolute strip offsets).

The new code is also faster and more robust.
As for the performance:
old decoder + conversion to rgb: fps = 2618
old decoder, without converting to rgb: fps = 4012
new decoder, producing rgb: fps = 4502
