Meltano

Wonder if I can get some help setting up a new tap: <https://github.com/anelendata/tap-bigquery#step-1-configure>
Struggling to work out how to translate the readme instructions to meltano config. Should the `tap_config.json` file be mapped into the config key in the meltano config?

My attempts so far are leading to:
```ELT could not be completed: Cannot start tap: Applying catalog rules failed: catalog file is missing.```
And my config:
```  - name: tap-bigquery
    namespace: tap_bigquery
    pip_url: git+<https://github.com/NiallRees/tap-bigquery.git>
    executable: tap-bigquery
    capabilities:
    - properties
    - state
    - catalog
    config:
      streams:
        - name: table
          table: 'project.dataset.table'
          columns: "*"
          datetime_key: "event_time"
      start_datetime: "2017-01-01T00:00:00Z"
    select:
    - table.*```

Don't forget to list `discover` among the capabilities!
