RFC: Input handling

[DerKarlos]

Define the needed inout handlers, and functions according to maplibre-gl-js. Create and document the demo input handlers (keys, mouse, touch) and separate them in an extra Rust crate. Add a set/interpolate API to the map code for the handlers. Check, if/what variations of winit, we need

💻 Examples

🚨 Test instructions

Check the maplibre-gl-js code, what input functions are exprected. Use the maplibre-gl-js UI and check if maplibre-rs has the same behaviour Use the exampel handler check if a variation is possible and the API documented.
