Added 3D model of Choke_EPCOS_B82722A.

Created by: jeremysiebers

This model is created by myself and is coupled to https://github.com/KiCad/kicad-footprints/pull/597. Dimensions are read from: http://www.farnell.com/datasheets/1860373.pdf?_ga=2.15642422.1600121449.1528266424-1651149783.1519657816

Thanks for creating a pull request to contribute to the KiCad libraries! To speed up integration of your PR, please check the following items as you complete them:

• A screenshot of the model(s) aligned with KiCad footprints is very useful
• Was the 3D model(s) created in a mechanical modelling program?
• Source files (or scripts) have been contributed
• Step model submitted in 1:1 scale
• WRL model submitted in 1:2.54 scale
• 3D model alignment checked against KiCad footprint
