Detailed topological information

[BDonnot]

TODO for this feature:

• being able to compute the position of the switches given the "topo_vect" vector (done, for standard importer for ieee grid)
• being able to compute the topo_vect / shunt_bus from the the position of the switches (super slow -loops in python- but working)
• being able to act directly on the switches (regular grid2op action)
• some work on the "observation" module, especially, to avoid translating topology over and over again between switches and "topo_vect"
  • make "topo_vect" a property
  • make a property for the switches
  • add two attributes that stores the switches configuration (if any) or the switch configuration (if any)
  • code the accessor of topo_vect / switch_position based on previous info
• documentation
• tests
• example on how to use this feature (would be in beta at first release)
• notebooks

/!\ in the case only the "topo_vect" info is given, the "switch_position" will be inferred from the topo_vect (and possibly the last known switch state). In this case we need to add a flag to say that it's not "THE" switch position but it's "A" switch position.

Then :

• integration with gym_compat module
• test
• doc
• performance improvment
