### Summary
- Add an optional `progress` callback to `Table.add(data, { progress
})`. Callback fires once per batch written and once more with `done:
true` when the write completes.
- Errors thrown from the user's callback are logged with `console.warn`
and swallowed
### Testing
- npm test
- ran smoke test script to verify functionality
