Add fasta to picard/collectalignmentsummarymetrics

[randombenj]

PR checklist

With this change one can add a fasta reference genome for alignment metrics summary:
https://gatk.broadinstitute.org/hc/en-us/articles/13832683660955-CollectAlignmentSummaryMetrics-Picard#--REFERENCE_SEQUENCE

Unfortunately this will be a breaking change as I couldn't find a way to add optional input parameters.

• This comment contains a description of changes (with reason).
• If you've fixed a bug or added code that should be tested, add tests!
• If you've added a new tool - have you followed the module conventions in the contribution docs
• If necessary, include test data in your PR.
• Remove all TODO statements.
• Emit the versions.yml file.
• Follow the naming conventions.
• Follow the parameters requirements.
• Follow the input/output options guidelines.
• Add a resource label
• Use BioConda and BioContainers if possible to fulfil software requirements.
• Ensure that the test works with either Docker / Singularity. Conda CI tests can be quite flaky:
  • For modules:
    • nf-core modules test <MODULE> --profile docker
    • nf-core modules test <MODULE> --profile singularity
    • nf-core modules test <MODULE> --profile conda
  • For subworkflows:
    • nf-core subworkflows test <SUBWORKFLOW> --profile docker
    • nf-core subworkflows test <SUBWORKFLOW> --profile singularity
    • nf-core subworkflows test <SUBWORKFLOW> --profile conda

Can we give the fasta channel a meta map, as is generally done for most modules (at least when they are updated). This helps with metagenomics pipelines where there may be more than one fasta file.

If you message on the github-invitations channel on the nf-core slack the workflows will run for you.
