Bump version of pion/sdp

Browse source 
Update our dependency on pion/sdp from v2 to v3, to match pion/webrtc
v3. This requires some changes in how we parse out addresses from ice
candidates. This will ease tor browser builds of snowflake since we are
now only relying on one version of pion/sdp instead of two different
ones.
