### Encode and Decode Polylines in Python

Source: https://github.com/zaczero/polyline-rs/blob/main/README.md

Demonstrates basic usage of the polyline-rs Python bindings for encoding and decoding polylines. It shows how to use both `encode_latlon` and `encode_lonlat`, as well as `decode_latlon` and `decode_lonlat` with a specified precision.

```python
from polyline_rs import encode_latlon, encode_lonlat, decode_latlon, decode_lonlat

line = encode_latlon([(38.5, -120.2), (40.7, -120.95), (43.252, -126.453)], 5)
assert line == "_p~iF~ps|U_ulLnnqC_mqNvxq`@"

coords = decode_latlon(line, 5)
assert coords == [(38.5, -120.2), (40.7, -120.95), (43.252, -126.453)]

coords2 = decode_lonlat(line, 5)
assert coords2 == [(-120.2, 38.5), (-120.95, 40.7), (-126.453, 43.252)]
```
