Python nu package

Integrate python features into nu.

Features

Python venv

This attempts to emulate bash's source .venv/bin/activate:

• update the path to prefer the venv's binaries
• clear the PYTHONHOME
• export VIRTUAL_ENV with a path to the venv

And adds a few extra features:

• adds src and tests to the PYTHONPATH

It allows stacking venvs (only the top one is active, but you can switch back a lot easier).

Usage:

• pyvenv activate (optional argument: specify which directory)
• pyvenv deactivate
• pyvenv list
