Added new FREYA_Data script (for refactor)
Added new raw data files, use pandas to do datasort functionality
Added time_period_id and gen_station_id identifiers functions
Renamed and moved a file
Added new solver, implementing using puLP and pandas at the moment

First equations have been implemented
Further additions to model
Further solver updates, bug fix to Data handling to ensure that the dataframe
indices are updated
Completed network broadcasting of dates
Updated network data generation, now broadcasts the number of pieces through the
dataframe as necessary for constructing piecewise linear losses
Added Unique piece naming, and calculation of piecewise linear losses
Changed transmission network indexing to use unique pieces
Added Losses to the solver
Added initial loop flow determination
Added all loops to network map, added stable loop sorter
Completed initial data manipulating using pandas, profiled at ~5x faster for current
use case
Added preliminary loop flow constraint to solver model
Initial solver functionality working, adjustments to network dataframe
Most functionality is working, debugging commencing
Attempting to fix an issue between WKM and WHI nodes
Problem fixed, appears to be a strange issue when zero priced offers are
setting the marginal price for energy, the model sees no issue with
arbitrarily increasing losses to maximise this variable
