submit package to conda-forge

[beenje]

epics-base 7.0.3.1 is now available on conda-forge. I think it'd make sense to have pvaPy there as well. It would ensure it's built with compatible versions of numpy and boost. I have a repo ready: https://github.com/beenje/staged-recipes/tree/pvapy/recipes/pvaPy

I'd like your approval before to submit it to conda-forge of course. And would other contributors be interested to be added as maintainer?
