Title: Susburrows/add region support amwg set6 new

Adds region functionality for plot set 6.

This required a small bug fix in uvcdat.py, because strideY was rounded down to zero, which is not allowable.

This was fixed by:
- self.strideY = int( nlats/nlatvs )
+ self.strideY = max(1, int( nlats/nlatvs ))
