Crashing due to GCP Pub/Sub API token expiration

[Vardominator]

When using the GCP Pub/Sub sink, Oura is crashing due to an access token expiration:

thread '<unnamed>' panicked at 'writer loop failed: PubSub { code: 401, message: "{\n  \"error\": {\n    \"code\": 401,\n    \"message\": \"Request had invalid authentication credentials.

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Is it possible to automatically refresh the access token without having to restart Oura?

@Vardominator FYI, latest version of the google pubsub lib seems to have implemented automatic token refresh. The lib has some breaking change, I'll work on applying them on Oura's side.
