[Feature Request] Easy seeding of spaces eagerx.BaseEnv

[jelledouwe]

🚀 Feature

Make it easy to seed eagerx environments (e.g. env.state_space.seed(seed)).

Motivation

Right now I need to do this to seed:

self._state_space = self.state_space
for key in self._state_space.spaces.keys():
self._state_space.spaces[key]._space.seed(seed)

which is a bit annoying.
