[qutebrowser] Using PyYAML in qutebrowser config

[artur]

Hey there!

I want to know if qutebrowser configs support importing modules
like PyYAML.

Why? Because Base16 usually uses YAML to package each of their
colorschemes, my idea is to read a YAML file into a string
then and then convert it into a python dictionary I can pass
to a function that themes qutebrowser accordingly.

As you might be able to infer, this would be a bit simpler than
converting a YAML file into a dictionary manually.

Cheers!
