Install packages to user path

pip3 install --user mercurial
pip install --user mercurial

This should result in the hg script being installed in $HOME/.local/bin/hg and the rest of the hg package in $HOME/.local/lib/pythonx.y/site-packages/.

The location on macOS was changed from $HOME/.local to $HOME/Library/Python
