Level 2 Velocity Dealiasing

[dpaulat]

When viewing level 2 velocity data, higher wind speeds show the wrong direction.

In order for proper velocity values to be displayed, the view should be dealiased. There should be an option in the radar toolbox to toggle the dealiasing on and off.

This can be done in PyART using the following method: https://arm-doe.github.io/pyart/notebooks/dealiasing_velocity.html
