Add bulk TPM output to scpca-nf

[jashapiro]

Closes #815

I was looking at scpca-nf, and realized that the changes to add TPM output were quite minimal, so I went ahead and did that. I left the count file name unchanged, despite its ambiguity, and simply added one more output file, in the same directory.

Since the script name seemed a bit out of date, I modified that as well.

Fun surprise, looks good!

I approved, but we should update this sentence too:

scpca-nf/external-instructions.md

Line 488 in 16fb37f

If bulk libraries were processed, a `bulk_quant.tsv` and `bulk_metadata.tsv` summarizing the counts data and metadata across all libraries will also be present in the `results` directory.

I guess we'll need some scpca-docs issues as well, but this won't make it to the portal for a little bit I imagine.

Turns out that document is a bit out of date... we probably want an issue to update it as well.
