Feat umi collapse

[CharlotteAnne]

Add new local module UMICollapse, removed UMI tools, du and UMI length checker logic.

Notes:

• We are using a third party docker container in the UMICollapse module, perhaps this ought to be changed, I'm not sure.
• Currently UMICollapse is not version controlled - I suppose the docker container is the only versioning we have for this - I've asked the author to start making releases so perhaps this will change in future, so I put the version.yml as NA.
• On the "two pass" param - apparently this increases runtime at the benefit of reducing memory footprint so whilst memory is an issue I've enabled it. In future we could remove this param to reduce runtime if that becomes an issue.

Looks like the QC fails because it can’t find the Dedup log now - is that easy to create with the new module?

cheers -- there is a log file created -- {prefix}_UMICollapse.log - can you see where i need to highlight this?

I have fixed the multiQC now so this is good to go.
