This is definitely something we will do. Hopefully we can prioritize it soon.

@apeltzer we had a meeting today and decided we will start working on implementing bclconvert support now. We will also do some refactoring to make it easier to add support for other demultiplexers in the future.

Until then, a work around is to run bclconvert with --output-legacy-stats=true and create a link to Reports/legacy in Data/Intensities/BaseCalls.

I think we can live with this for now, we'll add support for CheckQC for bclconvert once this is done in nf-core/demultiplex
