Upgrade to version 1.7.1

[BDonnot]

Breaking changes

• The possibility to propagate keyword arguments between the environment
  and the runner implied adding some arguments in the constructor of
  PandapowerBackend. So if you made a class that inherit from it, you should
  add these arguments in the constructor (otherwise you will not be able to use
  the runner) [This should not impact lot of codes, if any]

Fixed issues

• a documentation issue Missing some keys when using GymEnv #281
• a bug preventing to use the FromChronix2grid chronics class when
  there is an opponent on the grid.
• a documentation issue Line Disconnection bug in _BackendAction fix #319
  on notebook 11
• some issues when the backend does not support shunts data (caused during the
  computation of the size of the observation) Tests are now performed in
  grid2op/tests/test_educpp_backend.py
• a bug when downloading an environment when the archive name is not the
  same as the environment names (attempt to delete a non existing folder). This
  is the case for l2rpn_wcci_2022 env. For this env, your are forced to use
  grid2op version >= 1.7.1
• an issue when converting a "done" action as a graph, see
  Error creating new variables using as_networkx() #327

New features

• score function for the L2RPN WCCI 2022 competition

Improvments

• adding the compatibility with logger in the reward functions.
• when there is a game over caused by redispatching, the observation is
  not updated, as it is the case for other type of game over (improved consistency)
• it is now possible to make an environment with a backend that
  cannot be copied.
• the arguments used to create a backend can be (if used properly)
  re used (without copy !) when making a Runner from an environment for example.
• description and definition of obs.curtailment_limit_effective are now
  consistent (issue obs.curtailment_limit_effective documentation is unclear #321)
