Recently there have been problems with Snowflake connectivity in Russia.
WebRTC data connections are being established, but then stop working
after some amount of traffic is exchanged. cohosh has investigated and
whatever the cause is, it's not straightforward DTLS fingerprinting.

Theodor, what's the status of your covertDTLS patch to Snowflake?
https://gitlab.torproject.org/theodorsm/snowflake/-/tree/covert-dtls-test
Is it ready to be run as a test client? If so, can you provide brief
instructions on how to do it?

Snowflake recently updated to pion/webrtc/v4, which I seem to recall was
a blocker for covertDTLS integration.
