Are threads (as per MSC3440) supported by this package? Is support planned?

Is your feature request related to a problem? Please describe.
This package doesn't seem to support MSC3440 Threads as per matrix-org/matrix-spec-proposals#3440

Describe the solution you'd like
It would be possible for a bot made using this SDK to send and receive messages as part of threads.

Describe alternatives you've considered
Grabbing the necessary thread data from the raw event.

Additional context
Threaded replies will be useful for features like: https://github.com/jakecoppinger/matrix-chatgpt-bot/issues/5

[turt2live]

Threads largely do not need dedicated SDK support, however the pieces that do are planned. There is no ETA on it being implemented - PRs would be welcome.
