Add support for cone shapes (backport #26)

[mergify[bot]]

🎉 New feature

Summary

Cone shapes were added to Ionic and backported to Harmonic in sdformat 14.4. This adds support for converting cone shapes between SDFormat and USD.

Test it

Attempting to convert the gz-sim shapes.sdf example world on main causes the conversion to fail with error messages like the following:

Error Code 2: Msg: Error parsing link [cone_link]
Error Code 7: Msg: Geometry type is either invalid or not supported

It works properly with this branch.
