r20200904

• Updated manual segmentations for T1w_MTS for r20200830
• Added derivatives for GM segmentation
• Updated exclude.yml after r20200830 results

Note: the log file shows many files with err.*, which is likely due to a problem of fetching the proper git version of SCT. There was nothing wrong with the processing itself (I think).
