Detect if the extractor didn't receive any events in X amount of time and error #62

This could mean Bitcoin Core has been restarted or is offline. We should exit the process. E.g. systemd can then restart it.

We should log a warning first, after maybe 2 minutes. Error after 5 minutes.

Went with 1 minute to warning and 3 minutes until exit in #63.
