Supporting NegMAS 0.10.0

• Upgrading to be compatible with NegMAS 0.10.0
• Adding step_with() to oneshot allowing for single counter-offer set stepping of the simulation (to be used to expose the simulation as RL and MARL environments later).
• Adding current_negotiation_details to OneShotAWI to get details of running negotiation
• Adding managed sales, supplies, total_sales, total_supplies, needed_sales, and needed_supplies to the OneShotAWI
• Extending OneShotState returned from awi.state and awi.default_state_encoder(mechanism_states) to expose more information about the simulation
