Slippy maps widget for egui.

Limitations

There are couple of limitations when using this library. Some of them will might probably be lifted at some point. Please raise an issue if you are particularly affected by some and I will try to prioritize.

• Limited to the OpenStreetMaps, but I want to enable other tile servers and protocols (like WMS) as well.
• It uses reqwests/tokio stack which does not work on WASM.
• Example for Android is missing, but it does work there.

Other suggestions are welcomed as well.
