fix several footprints to support pre-existing 3D models
Created by: jkriege2
I re-uploaded several pre-existing 3D models that were not yet (correctly) part of the packages3D repo. For this to work, I had to change some footprints, which are in this supporting PR.
3D model-PRs, see: https://github.com/KiCad/kicad-packages3D-source/pull/76 & https://github.com/KiCad/kicad-packages3D/pull/213
remaining KLCs:
- DWM1000 due to unsymmetrical distribution of pads, but should be OK this way. The anchor is in the center of the actual module!
