Example for two way communication with a background goroutine

[mdepot]

This is to request a new example showing two way communication between bubbletea and a background process (running as a goroutine.) There are already two examples (send-msg and realtime) which demonstrate one way communication with bubbletea, however it would seem to be a common use case to need two way communication.

For example, the background process may do some work and need to be able to push updates into the model so that the results can be displayed in the interface. But it also makes sense that the background process might want to change its behavior based on the user interacting with the interface, meaning it also needs to also be able to pull information from the model. It would be great to have an example showing this two way communication, a background goroutine that changes its behavior based on flags in the model, as well as the model being updated based on work done in the background goroutine.

@mdepot This is a great idea I think! Are you working on a potential PR for this?

Great idea. This would be really useful (and fun to make).

I've submitted a PR that includes an example addressing the requested use case. I would greatly appreciate your insights and feedback!
