For the 0.22 release we'll want to start hardcoding Torv3 addresses instead of (or in addition to) Torv2.

The biggest challenge here is not how to hardcode them, although that will require a few minor script and code changes, but how to collect them. The release process is to get the addresses from DNS seeders, however these currently don't support the `addrv2` message nor Torv3 addresses in the first place. Nor do they really have a need to.
