More specifically: - Add async `aroute` function (i.e. async version of `route`) to the `RouterChain` which calls the routing LLM asynchronously - Implement the async `_acall` for the `LLMRouterChain` - Implement the async `_acall` function for `MultiRouteChain` which first calls asynchronously the routing chain with its new `aroute` function, and then calls asynchronously the relevant destination chain. <!-- If you're adding a new integration, please include: 1. a test for the integration - favor unit tests that does not rely on network access. 2. an example notebook showing its use See contribution guidelines for more information on how to write tests, lint etc: https://github.com/hwchase17/langchain/blob/master/.github/CONTRIBUTING.md --> ## Who can review? - @agola11 <!-- For a quicker response, figure out the right person to tag with @ @hwchase17 - project lead Async - @agola11 -->
