Client send datagram support.

[needon1997]

Notice currently only server side support sending datagram, I think it would technically the same code if we want to support such in client side?

Isn't the extension that's already in master ready to be used? If so, is there anything we could help with to get a crates.io release of the h3-quinn and h3 crates that would include the datagram support?

Nope, I am horribly mistaken. Would it be OK to submit a PR to expose datagrams to client connections too? We're looking to implement an RFC 9298 compliant client, so we have a hard dependency on being able to send datagrams from a client connection.

That is, what this issue is about. A PR would be great.
Please keep in mind, that there are yet unreleased changes on master, which move the datagram logic to a seperate crate within this reposetory.
