Citylearn

This release addresses 2 main issues:

1. The long simulation time as a result of time series variables being recalculated every time step has been solved.2. Simulations, especially with RBCs are much noticeably faster to complete.
2. There was a bug in the calculation of the battery energy balance that overestimated the energy balance during discharge.
3. Other minor issues.

Credits to ludwigbald for finding and proffering solutions to the issues.
