Support Conda-style packaging?

[woodruffw]

It might be nice to support Conda-style packaging directly. I don't know too much about Conda, so some questions that will need to be answered:

1. Does Conda have any notion of abi3 compatibility, or a way to signal which Python version a package is abi3 compatible with?
2. Does Conda's normal package tooling include the .abi3. infix on shared objects?

To the best of my knowledge:

1. Not officially, but it can be "implemented" with some workarounds. We can also work on conda to make it happen. See Support for abi3 Python packages with abi3audit checks conda-forge/conda-forge.github.io#1865.
2. conda ultimately relies on whatever building tool you use under the hood (setuptools, etc), so it shouldn't be a problem.
