chore: Release v0.2.21

This release brings 2 great featues. First, the abillty to disable DNS lookups, which has been a long requested security feature, which we plan to default to in an upcoming version.
Second, there is an network profiler, which tallies up sent and received network packets.

Beside these features we also have fixes like a 75% memory usage reduction for NGCs and connecting to NGC with a password if we are already joined, which might be necessary if a password was set or changed while you where away.
Furthermore, we now have better localhost discovery, which means that nodes on the same system find each other.

---

If you have not yet upgraded to the previous release (0.2.20), you absolutely should, as it fixes a security issue. All releases before 0.2.20 used VBR opus encoding, which is susceptible to transcription attacks. ( see #2757 )
