chore: upgrade deps and attempt to enable using go1.19 (#869)

* upgrade to our go.mod enabled of psiphon-tunnel-core such that
we're now using v2.0.24 of the tunnel-core;

* upgrade to the latest lucas-clemente/quic-go release;

* upgrade to the latest ooni/oohttp release (which is based on go1.19
but the diff seems good enough to continue using go1.18.x as well);

* upgrade to the latest ooni/oocrypto release (for which we can make the
same remarks regarding using go1.18.x);

* deal with changes in lucas-clemente/quic-go API as well as changes
in what a go1.19 *tls.Conn compatible type should look like.

Unfortunately, we cannot switch to go1.19 because psiphon forks quic-go
and their fork's still not building using such a version of go.

Part of ooni/probe#2211.
