Feature

Abbility to install typeshed stubs from pylock.toml

Pitch

In our project we want to run mypy against system installed packages which vary on each distribution. We can create the pylock.toml file or equivalents from the current environment so we can have a list of all the installed packages. What we are missing though is a helper that would go through this list and install all possible stub files with appropriate version lock matching the installed ones so that it guarantees to not alter (upgrade/downgrade) the currently installed packages.
