Error if a package only has wheels in pypi

[alexvorobiev]

faiss is an example:

$ python-package-init faiss
Fetching package="faiss" version="stable"

can confirm, this is quite unfortunate. @costrouc do you have an idea how to proceed here?
maybe at least we could write out a more useful error message.

[costrouc]

Yeah this should be fairly easy to implement. I can't promise I have the time right now to implement that. Wheels actually have more information on them than sdists to we should be able to get more accurate requiements
