Added 3D model to the Cliff FCR7350x connectors. All colours.

I finally found the time to create a 3D Model for the Cliff FCR7350G. I did them in all colours available and also added individual footprints for each 3D model so that this work out of the box.

The model was created form scratch based on the tech drawing provided by Cliff.

• A screenshot of the model(s) aligned with KiCad footprint(s)
• Source files are contributed on the apropriate location
  • Link to the package3d-source pull request or to the script pull request
• Step model submitted in 1:1 scale
• WRL model submitted in 1:2.54 scale
• 3D model alignment checked against KiCad footprint
• WRL model uses correct material properties
• Geometry check performed on the model

Be patient, we maintainers are volunteers with limited time and need to check your contribution against the datasheet. You can speed up the process by providing all the necessary information (see above).
