add seq_type to anarcii module

PR checklist

Adds seq_type as an input to anarcii, passed to the tool's -t flag.

-t/--seq_type defaults to antibody. The module never sets it, so numbering other input needs an ext.args override that is easy to omit, and getting it wrong is silent: ANARCII returns unnumbered chain F instead of erroring.
That's why I consider that the flag should be part of the nf-core modules. Also, AFAIK no pipeline uses it yet (mine will very soon :D), so PR won't break anything

• This comment contains a description of changes (with reason).
• If you've fixed a bug or added code that should be tested, add tests!
• Follow the naming conventions.
• Follow the parameters requirements.
• Follow the input/output options guidelines. (I hope, unsure if meta-maps are required for all inputs??)
• Add a resource label
• 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
