0.5.7

Added

• gcloud: Allow passing extra_scopes to Google OAuth2.

Security

• Fix RUSTSEC-2024-0003, a
  Denial of Service vulnerability which could apparently cause a hostile HTTP
  server to cause out-of-memory errors in a client. Since dbcrossbar is
  unlikely to connect to many hostile HTTP servers, this is probably a low-
  priority fix for almost all users.
