The geo-types library provides geospatial primitive types and traits to the GeoRust
crate ecosystem.
In most cases, you will only need to use this crate if you're a crate author and want compatibility
with other GeoRust crates. Otherwise, the geo crate re-exports these types and
provides geospatial algorithms, while the geojson crate allows serialising
and de-serialising geo-types primitives to GeoJSON.
