(v3.6.2) - EPW processing: Replace opyplus module by epw

[AlejandroCN7]

Description

This update replaces the functionality provided by the opyplus library with the new library called epw.

Opyplus includes a lot more features beyond the processing of EPW files for climate data. Sinergym stopped using these additional features a while ago. Moreover, opyplus has issues with warning messages in the latest versions of pandas.

Therefore, we opted for a more minimalist and focused installation, precisely tailored to what Sinergym needs, using the epw library.

It has been verified that variable changes are effective with the new library, ensuring that the tool functions exactly the same. Additionally, the documentation has been updated to include a list of energy variable names accessible through this library, as these names differ from those in opyplus.
