Release geoarrow v0.3.0 (#705)

If it's ok, I'd be stoked to get a v0.3.0 release of **geoarrow** — some
of my **stac-geoparquet** is getting close to being release-able.

Here's a checklist of things that have been mentioned as part of a v0.3
(including
#628 (comment)
and https://github.com/geoarrow/geoarrow-rs/milestone/3):

- #660 is done ✅ 
- Some (but not all) of the doc updates are done in
#696, and I've got a
tracking issue for the rest in
#689
- "Broader support for 3d geometries" isn't done as far as I know, but I
haven't really been touching that at all yet
- #539 is a Python thing,
not a Rust crate thing

As a part of this release PR I've updated our deps when possible (`sqlx`
will require code change to support an update so I haven't done that
one).
