Make output compatible with nf-core/scflow

nf-core/scrnaseq feature request

Describe the solution you'd like

Would be great to generate (extra?) output for the nf-core/scflow pipeline that allows using the output matrices from this pipeline directly in the scflow pipeline as input 👍🏻 @combiz and I discussed that a bit in the #scflow channel on slack.

Would require some bits added, but shouldn't be too much extra effort and would enable direct downstream analysis for quite some projects - which would benefit both the scrnaseq users and scflow users ;-)

A crucial part of the work we've done for #156 is to convert the output of scrnaseq to 10x barcodes features matrix format, which is the same input as scflow requires, so we can make a separate PR with this conversion before completing the Cellenics integration.

scflow seems pretty rather dead and there hasn't been a lot of interest in this issue. Closing for now - If someone thinks differently, feel free to reopen.
