(v3.6.5) - Functionalities to take energy costs into account.

[fpertinezp]

Description

These changes allow the addition of the energy cost term both in the calculation of the reward function and in the observation of the environment.

Motivation and Context

Incorporating energy cost into the reward function and environment observation enhances the agent's ability to balance performance with energy efficiency, which is vital for minimizing operational costs and environmental impact.
