Manifest Validation

manifest	result	expectation
GenomicsAssayTemplate_0.csv	😄	Lists can be blank if attr not required using ‘list like’ rule
GenomicsAssayTemplate_1.csv	😄	Mixing blanks and regular list values works
GenomicsAssayTemplate_2.csv	😄	Conditional validation for attributes is currently not supported
ScRNASeqTemplate_0.csv	😄	Single list val works by using ‘list like’ rule
ScRNASeqTemplate_1.csv	😄	Fail because of missing data in required field libraryStrand
