Add primerprospector_analyzeprimers

[vagkaratzas]

Workaround shim in main:

Primer Prospector 1.0.1 (this is an old codebase) is a Python 2 package and the BioContainer entrypoint uses Python 2.7.
The bug is specifically Python 2 behavior: range() requires integer arguments, and the package passes a
numpy.float64 during plotting.

PR checklist

• 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.
• Broadcast software version numbers to topic: versions - See version_topics
• 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

Thanks @vagkaratzas ! This looks useful.

I have one major issue with this module relating to incorrect handling of output hit files when there are multiple primers in the input primer file (a common case). The tests should be amended with this case.

I think it would be useful to support gzipped fasta inputs, but I don't know what nf-core good practice says about that.

For multiple primers in the input primer file this will cause an error or overwrite some results. Rather all the files should be emitted in the hits output channel. If prefix renaming is desired then it needs to be performed on each of the produced hits files.
