Add AMRfinder plus to atavide

The tool is found at AMRFinderPlus

You can find the tool at ncbi-amrfinderplus
See their [wiki](https://github.com/ncbi/amr/wiki/Install-with-bioconda]

Note: we need to consider adding protein calls (e.g. prokka?) and then using the AMRfinder plus HMMs. Note that genbank_to might help with the AMR finder GFF input
