"the augmentation engine shifts" are specified as [-6,6] ! they should be [-6,5]

Hi there!

In the 00 - Augmentation.ipynb file you create the augmentation engine by specifying the number of shifts as n_semitones=[-1, 1, -2, 2, -3, 3, -4, 4, -5, 5, -6, 6]. Well, let's say our audio file (the song) is in the key of C major so following the shifts we get B(-1 down), Db(+1 up), Bb(-2 down), D(+2 up), A(-3 down), Eb(+3 up), Ab(-4 down), E(+4 up), G(-5 down) , F(+5 up) , Gb(-6 down), Gb(+6 up) ! as we can observe, we have Gb twice! (-6 down and +6 up) ! The number of semitones shifted should be n_semitones = [-1, 1, -2, 2, -3, 3, -4, 4, -5, 5, -6]. In the Crema package the number of shifts is correctly specified as -6 to + 5 semitones! https://github.com/bmcfee/crema/blob/master/training/chords/00-setup.py. Is it correct to assume that the number of semitone shifts here should indeed be n_semitones = [-1, 1, -2, 2, -3, 3, -4, 4, -5, 5, -6] ???

So every File should create 11 unique deformations and with the original file added, we should have 12 files and not 13 files??
