- Before: 'OFFSET' = 2nd measure fumenOffset
- After: ('OFFSET'-Full measure duration) = 1st measure fumenOffset
Both methods will produce the same results if no #MEASURE/#BPMCHANGE
commands are present in the first two measures. However, if these
commands ARE present, then you will get wildly different results.
This change doesn't affect 4/6 tests, but for 2/6 tests there were
#MEASURE/#BPMCHANGE commands. For these songs, I had erroneously "fixed"
the OFFSET values, when they were correct all along. So, I reverted them
back to their original values.
Fixes#25.
