set variable starting conditions

For the following FMU Export settings, the starting conditions, e.g. temperatures in buffer storages, can not be set for any episode when using the fmu.py simulator:

FMU Version 2.0, Type: Co-Simulations using Dymola Solvers, Dymola Version: 2021

The FMU parameters were checked and are defined correctly in the model. For simulation speed and performance reasons, this export type can be useful, which is why the initial starting conditions should be changed in eta_utility.

My suggested solution:

call self.set_values(init_values) before entering the initialization mode with self.fmu.enterInitializationMode() in __init__ as well as the reset function.

This solution was tested with the used FMU as well as the standard FMU models from supplysystem a and supplysystem b
