[FR] Python Security Rules Unit Testing #914

Is your feature request related to a problem? Please describe.
I am using a Python Firebase Functions Backend for My Application but I would like to Unit Test My Firestore Security Rules. There doesn't seem to be a supported library for this in Python.

Describe the solution you'd like
Provide a similar library like is provided for NodeJS: https://www.npmjs.com/package/@firebase/rules-unit-testing/v/3.0.2-canary.6d31930b3

Describe alternatives you've considered
It may be possible to setup the testing manually without the supported helper methods. I may have to separate my security rules unit testing to another repo and use NodeJS.
