Move conda recipe to separate feedstock repository

[wtbarnes]

The conda-recipe folder should live in a separate "feedstock" repo (e.g. for the aiapy package: https://github.com/conda-forge/aiapy-feedstock). The feedstock repository is then updated every time a new release is made on PyPI and once merged, propagates a built version of the package to conda-forge. This may be a bit premature given that the package is not yet on PyPI.
