MSAF Beta v0.1.5

• Fixed bug tha threw a TypeError if multiple algorithms were run in a single JAMS file with None and other label_ids in it
• Added new vmo oracle segmentation method (by Cheng-i Wang, thanks!)
• Adapting sonify function to latest numpy
• Using KMeans from sklearn instead of scipy for 2D-FMC. Results are better
• Making sure we are never using more number of clusters than number of segments for 2D-FMC
• Added new parameter 2dfmc_offset in the 2D-FMC method
• Using np.inf normalization for 2D-FMC now, since it seems to yield better results (at least for Beatles TUT)
• Padding beat-sync features now, seems to fix potential misalignment of boundaries. Some algorithms (2D-FMC, CNMF) seem to yield better results now
• Modified features file: two new fields may be addeed: est_beatsync_times and ann_beatsync_times.
• The member variable _framesync_times in the Features was never updated. Fixed it
