Test models for creation of synthetic wave data

[Rosejoycrocker]

• currently models have been created for synthetic site data, connectivity and dhw data.
• wave data is also a necessary input layer for the ADRIA model
• first try out temporal model from SDV package, then try out models from Deep Echo package if no success.

Addressed by genericising the dhw data model in env_PAR_model.py
