Fix: IEEE 4068: add NC pins and footprint filters

John Beard requested to merge johnbeard/kicad-symbols:4068_nc into master

Fix for #3249 (closed).

While S4.5 says you can omit NC pins, it also says you should only do it when there isn't space, and also then you have to add to the footprint filters. This part has space, and also has no fooptrint filters set. So:

  • Set FP filters for 2 SO Packages, DIP and SSOP from the DS (there isn't a FP for the CDIP yet)
  • Add NC Pins
  • Align all pins to 100 mil grid
  • Change all pin lengths to 200mil (side pins were 300 mil)
