Is your feature request related to a problem? Please describe.

I am running an async codebase, and alpaca-py is blocking

Describe the solution you'd like.

Either expose an async client (httpx is great), or add to the documentation a discussion of the concept (for example, workarounds, thread-safety, etc).

Describe an alternate solution.

Anything else? (Additional Context)

Y'all are doing great work. Thanks!

All they need to do is make _run_forever() public and stop swallowing the general Exception type there

To be clear, this request REALLY should be implemented. It is a basic async app requirement that the task should be manageable externally, because real-world async apps will usually already be running in with an asyncio context, and therefore need to start/stop and handle exceptions externally. It's shocking (telling?) more people don't need this.... I will provide a good backwards-compatible PR if someone at Alpaca can confirm I should.
