According to https://docs.python.org/3/library/random.html, we are missing the following random generators

• choices (added in Python 3.6)
• randbytes (added in Python 3.9)
• triangular

As well as the classes to get generators without shared states

• Random class
• SystemRandom class

And the getter/setter

• seed
• getstate
• setstate
