Add task.ext.args to phantompeakqualtools and finish the module

[JoseEspinosa]

As explained here, when the data set is too big the phantompeakqualtools throws an exception. Adding the option fixes the problem --max-ppsize=500000. On this PR, task.ext.args to the phantompeakqualtools command and also, all the missing bits of the module were added (tests + meta.yml file)

PR checklist

• This comment contains a description of changes (with reason).
• Ensure that the test works with either Docker / Singularity. Conda CI tests can be quite flaky:
  • PROFILE=docker pytest --tag <MODULE> --symlink --keep-workflow-wd --git-aware
  • PROFILE=singularity pytest --tag <MODULE> --symlink --keep-workflow-wd --git-aware
  • PROFILE=conda pytest --tag <MODULE> --symlink --keep-workflow-wd --git-aware

So you went with args and not args2 too? It can be changed later if required.

Yep thought it was going to be more simpler since there are no other arguments passed to the tool
