Timeout (#58)

<!-- This is an auto-generated comment: release notes by openai -->
### Summary by OpenAI

**Release Notes**

- New Feature: Added `timeoutMs` option to the `opts` object passed to
the `sendMessage` method in the `Bot` class.
- Refactor: Renamed the `turbo` property to `api`.
- Refactor: Assigned the result of calling `this.api.sendMessage` to the
`response` variable instead of `this.turbo.sendMessage`.
- Chore: Added logging statements for debugging purposes. 

These changes improve the functionality and maintainability of the
codebase.
