Encode and decode polyines in Rust using this package.
Polyline encoding is a lossy compression algorithm that allows you to store a series of coordinates as a single string. Point coordinates are encoded using signed values.

``rust
const encoded = "_p~iF~ps|U_ulLnnqC_mqNvxq@";
println!(polyline_codec::decode(encoded, 5).unwrap());
// [
// LatLng(
// 38.5,
// -120.2,
// ),
// LatLng(
// 40.7,
// -120.95,
// ),
// LatLng(
// 43.252,
// -126.453,
// ),
// ]
const path = [ (38.5, -120.2), (40.7, -120.95), (43.252, -126.453), ]; println!(polylinecodec::encode(path, 5).unwrap()); // "p~iF~ps|UulLnnqCmqNvxq`@" ```
