Support for NuGen Ovation RRBS libraries

[jma1991]

This pull request introduces an initial implementation for processing NuGen Ovation RRBS libraries, drawing guidance from the commands outlined in the NuMetRRBS repository. Currently, the focus is on integrating fundamental steps such as adapter trimming and diversity trimming. Although there's an optional component for deduplicating reads via molecular tags, I'm not sure how to implement this right now. Lastly, let me know if I should submit some Ovation data to the test-datasets repository.

The suggested diversity trimming looks good to me, but do we have specific test data for this?

I have some Ovation test data, shall I submit it to the test-datasets repository?

@jma1991 could you please update / rebase this PR off the latest nf-core dev branch please?

@jma1991 checking in here - did you get some test data into the test-datasets repo ?
