Non-US location support for BigQuery

[archiewood]

Currently you cannot set a region for your BigQuery database, so only the default region (US) is usable

See an implementation in https://github.com/evidence-dev/sqltools-bigquery-driver/blob/264f413ea75450f6217d54567c0bb1c4f75cff70/src/ls/driver.ts#L44

@plotti we don't have this in progress yet. If you're willing to contribute this, that would be awesome!
