bug in config.py

[Oliver Ziff]

Hi there, just to let you know the config optional section in the documentation does not work with the current version of majiq. Gives rise to error:

  File "/majiq2/lib/python3.8/site-packages/rna_majiq/src/config.py", line 207, in __init__
    op_id, op_val = opt.split(":")
ValueError: not enough values to unpack (expected 2, got 1)

[optional]

Hippocampus1=strandness:None,

Liver2=strandness:reverse,

should to be modified to:

[optional]

Hippocampus1=strandness:none

Liver2=strandness:reverse

- commas removed from end of line

- None changed to lower case none

or alternatively the config.py needs correcting.
