BioC dep "not available for R 3.6" (it's available)

Tried to remedy this by adding:
“biocViews: RNASeq” to DESCRIPTION, no dice.

Ended up removing BiocSingular (imports for my actual package only included BiocSingular reverse imports), then removing all version numbers for BioC imports, now it seems to build ok
