v0.18.0 Release

• Added pb.backups.upload(data) action (available with PocketBase v0.18.0).

• Added experimental autoRefreshThreshold option to auto refresh (or reauthenticate) the AuthStore when authenticated as admin.
  This could be used as an alternative to fixed Admin API keys.

  await pb.admins.authWithPassword("test@example.com", "1234567890", {
    // This will trigger auto refresh or auto reauthentication in case
    // the token has expired or is going to expire in the next 30 minutes.
    autoRefreshThreshold: 30 * 60
  })
