Fixes * correctly set the invalidation bits in the channel group record when appending/extending signals with invalidation bits * documentation fixes
Changes * _scramble_ method will now create a new file thus preventing accidentally overwriting the original file * performance optimizations when dealing with channels that have invalidation bits
4.1.2
Fixes * fix error in case of overlapping big endian channels * fix for isuue 97 * set proper program identification in file header
Changes * implement _scramble_ method for MDF v2 and V3 * some performance optimizations
4.1.1
