v0.5.0

• Rewrote bridge in Go.
  • To migrate the bridge, simply upgrade in-place. The database and config will be migrated automatically, although some parts of the config aren't migrated (e.g. log config). If you prevented the bridge from writing to the config file, you'll have to temporarily allow it or update it yourself.
  • The bridge doesn't use signald anymore, all users will have to re-link the bridge. signald can be deleted after upgrading.
  • Primary device mode is no longer supported, signal-cli is recommended if you don't want to use the official Signal mobile apps.
  • Some old features are not yet supported (e.g. group management features).
• Renamed main branch from master to main.
• Added support for edits and message formatting.
