 * Unify various line measurements under new `line_measures::{Bearing, Distance, Destination, InterpolatePoint}` traits

-  GeodesicBearing::geodesic_bearing(p1, p2)
-  HaversineBearing::haversine_bearing(p1, p2)

+  p1.geodesic_distance(p2)
+  p1.haversine_distance(p2)
+  p1.euclidean_distance(p2)

   After:
   ```
-  use geo::{Geodesic, Haversine, Bearing, Distance};
+  use geo::{Geodesic, Haversine, Euclidean, Bearing, Distance};
   Geodesic::bearing(p1, p2)

   * <https://github.com/georust/geo/pull/1216>
 * Deprecated legacy line measure traits in favor of those added in the previous changelog entry:
   * `GeodesicBearing`, `GeodesicDistance`, `GeodesicDestination`, `GeodesicIntermediate`
   * `RhumbBearing`, `RhumbDistance`, `RhumbDestination`, `RhumbIntermediate`
   * `HaversineBearing`, `HaversineDistance`, `HaversineDestination`, `HaversineIntermediate`
+  * `EuclideanDistance`
   * <https://github.com/georust/geo/pull/1222>
+  * <https://github.com/georust/geo/pull/1232>
 * Deprecated `HaversineLength`, `EuclideanLength`, `RhumbLength`, `GeodesicLength` in favor of new generic `Length` trait.
