Description

Right now the compex clearing supports only pay as clear and with the nodal clearing removed we no longer have an option for zonal clearings with pay as bid option. This PR addresses this issue by including this functionality to the complex clearing

Changes Proposed

-add pricing mechanism as param_dict argument
-move log_flows also to the param_dict
-update the docstrings for better explanation
-rename the market clearing to complex clearing
-rename it in config files and add param_dict for demonstration

• run pre-commit (apparently this was not done before the release)
