rust-wkb

This crate provides functions to convert rust-geo geometry types to and from Well Known Binary format, i.e. ISO 19125

Examples

```rust use geo_types::; use wkb::;

let p: Geometry = Geometry::Point(Point::new(2., 4.)); let res = geomtowkb(&p); assert_eq!(res, vec![1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 64, 0, 0, 0, 0, 0, 0, 16, 64]); ```

You can also 'read' a Geometry from a std::io::Read:

```rust use geo_types::; use wkb::;

let bytes: Vec = vec![1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 64, 0, 0, 0, 0, 0, 0, 16, 64]; let p: Geometry = wkbtogeom(&mut bytes.asslice()).unwrap(); asserteq!(p, Geometry::Point(Point::new(2., 4.))); ```

Adding proper *Ext traits is planned.
