Incorrect interpolation of wind direction in ReaderTMY3

[mwetter]

The wind direction is interpolated incorrectly if the weather data file has a transition between 360 degree and 0 degree.
This is reported in
lbl-srg/modelica-buildings#4417

As the interpolation is directly obtained from the data reader, which reads the weather data file into memory during its constructor, a correction is probably to update the weather data conversion from .epw to .mos so that the .mos file has no such transition. E.e., time series of the form

t    angle
0   359
1    1

would be converted to

t    angle
0   359
1    361

@kbenne: FYI, here is the issue with the weather data reader

@mwetter I am almost done implementing this change, which will also include updating the weather file converter from Java to Python. However, I have a question on the weather files to convert. The weather files in IBPSA/Resources/Data/BoundaryConditions/Validation belong to the weather BESTEST suite, should they be updated too or kept the same as the original values provided?

@EttoreZ : It is fine to update the .mos files as tools can convert the original weather data to the format that the tool requires.

Sounds good. Then I will modify all the existing .mos files.
