Improved Wind Rose Plot (v2)

Improved Wind Rose Plot v2

This is a reimplementation of the code changes proposed by @cfrontin in #968 but built on the develop branch instead of main (something about running that way is triggering some errors, and anyway breaks our convention). Running for example the wind_data_user notebook changes the look of wind rose plots from:

To:

Which is an improvement to my eye. Thanks @cfrontin for the submission!

Note that merging this PR could potentially introduce a breaking change for a very small number of users. The ax returned by the plot() method will now no longer contain a legend (and instead a colorbar). Any code that subsequently obtains and modifies the properties of the legend will no longer work.

While this is indeed a breaking change, and therefore against the rules of semantic versioning that we try to adhere to with FLORIS, we feel that this is a small enough change that it will affect very few (and quite possibly no) users, and are going to proceed to merge under the same major version of FLORIS (v4).

If this change affects you negatively, please let us know by commenting on this PR and we will search for a resolution.
