What's Changed
- Bugfix: Correct sampling in LoadShedding and MaxRenewable environments (only relevant for uniform and normal sampling)
- Introduce explicit state space definition (for data sampling)
- Simplify creation of multi-stage and security-constrained envs by adding separate classes for these cases to inherit from
