Add D_QFN_3.3x3.3mm_P0.65mm

evanshultz requested to merge github/fork/evanshultz/d-qfn3.3 into master

Datasheet: https://www.wolfspeed.com/media/downloads/846/C3D1P7060Q.pdf

The datasheet is poorly done with regards to dimensions but I got confirmation on everything. The NC pin on page 5 is 0.34mm wide. Page 6 is showing the package pins in dotted lines and the recommended copper pads in solid lines. You can use the dimensions on page 5, then add the 0.05mm swelling, to figure out missing dimensions on page 6.

I believe this is only the 3rd time I've tried the polygon pads. While I believe it is correct, please let me know if there are better ways to use this feature.

I didn't dimensions because KiCad StepUp doesn't support polygon pads. (Yet?)
