deps(relay): bump to stun-codec 0.3.3 (#2088)

I've opened several PRs upstream for code that was missing in
`stun-codec` for our purposes. Those have been accepted and released, so
we can bump to that version now and remove that code.

A big thanks to @sile for the crate and being responsive maintainer
