Polar plot method

Closes #179

moved polar plot method from LadybugTools_Toolkit to here. Also added ability to view the summed totals of values for use with plotting anything other than wind roses (for instance a radiation rose would be more useful to show total radiation from a direction, rather than the probability it happens), implemented through the density bool.

The implementation is necessarily different to how it works in LBT (due to not being linked to a dataset through the Wind class), so data is input as a dataframe, and the method reads the values and directions columns specified.

Removed other_data as an input, as now that was a workaround for the Wind class to create roses from data that was not in the wind object itself (basically moving the polar plot method to Python_Toolkit made it redundant). See the linked LBT PR for more info.

Renamed other_bins to value_bins (as it is easier to tell what it actually means this way)

Test files

run the unit tests in LBT Toolkit
When unit tests for this method are made, run those as well.

Do a spot check with some openmeteo data in jupyter to check that it all works.
