sidewinderd - experimental support for Logitech G710+

Today I was able to get the Logitech G710+ working with sidewinderd. You can find the experimental branch at the project's GitHub page (https://github.com/tolga9009/sidewinderd/tree/lg-g710).

Special thanks to nirenjan, for his extremely well written documentation about the Logitech G710+ (https://github.com/nirenjan/g710plus-linux).
