Heltec V3 Case (Amended)

This is an amended version of Bunny Winkles’ awesome Heltec V3 case.  This design makes it slightly easier to install the Antenna by providing a slightly easier path to route the pigtail and not to stress the sma antenna cable junction quite so much.  I also increased the size of the battery cable hole so I can avoid having to solder.

remix was to slightly ease the routing of antenna and battery cables through the case
