Create config.yaml for easy conda install

[ammaraziz]

Hi,

I would like to recommend you include a yaml file in the github directory to allow for easy installation of VAPiD. There's a number of dependencies, which I think conda can install all of them.

To install from the yaml file:

conda env create -f conda.yaml

contents of conda.yaml:

name: vapid
channels:
  - conda-forge
  - bioconda
dependencies:
  - python=3.9
  - pip
  - biopython
  - numpy
  - tbl2asn
  - mafft
  - blast
