[IMPROVEMENT]: DRL_battery.py script - parameters improvement

[AlejandroCN7]

Improvement 🔧

In order to make experiments with sinergym more easily and in view of being able to expand the set of algorithms and hyperparameters used, it is proposed to change the definition of these parameters to a YAML or JSON structure. Thanks to @Melon-PieldeSapo for the idea :).

Original behavior

Current call to experiment:

python scripts/DRL_battery.py --environment ... --algorithm ... --evaluation ...

Enhanced behavior

For example:

python scripts/DRL_battery.py -conf experiment_config.json
