CSV filter output for multi-value sample attributes

[nsheff]

If you have a sample with an attribute with multiple values, the CSV writer will write them into a CSV in a python list form:

eido convert https://raw.githubusercontent.com/pepkit/nf-core-pep/master/samplesheet_test.csv --st-index sample -f csv

Result:

Found 2 samples with non-unique names: {'WT_REP1', 'RAP1_UNINDUCED_REP2'}. Attempting to auto-merge.

Might make more sense to do this in the way of multiple rows per sample, for the purposes of the CSV filter :vomiting_face:

I believe this was fixed in https://github.com/pepkit/eido/pull/43
