Add dataframes, variables, and constraints to include max/min energy outgoing flow for assets, using the base periods

[datejada]

Part of Epic issue #526. Steps:

• Create the dataframe from the partition definitions for the variables and constraints. If there is no defined profile, there should be no constraints. We should apply this type of constraint if we have the data; otherwise, they are superfluous.
• ~Create the energy variables e.g,. asset_outgoing_energy_flow_inter_rp (or a better name, and also maybe for the incoming energy flow, depending on the asset)~ No need of extra variables here
• Create the constraints for the maximum and minimum energy limit
• Update the outputs of the model
• Benchmark the changes to identify improvements
