Selected Detent using Binding

[mlengert]

Hi, at first, thanks for this amazing library. It seems to be the best backward compatible SwiftUI implementation :)

I saw that your code internally uses @Binding for the selected detent. Is there a way to bind a value outside of your implementation to get informed if the user changes the selected detent by dragging. Additionally, if I change the selected detent programmatically, it looks like the selected bottom sheet detent didn't change at all.

For that it would be amazing if you could implement a solution similar to the native apple interface where the selected detent is a Binding object.

@mlengert the environment variable should do that as mentioned in the docs. the second issue could be due to changes they made in their official verison. PRs are welcome.

@ericlewis thanks. The documentation is not really precise at this point. It is primarily a reference to the iOS documentation without mentioning any available env-key.  However, I was able to make it work with the Environment(\.selectedDetentIdentifier) variable and a custom modifier. With that, I was also able to fix my problem where the programmatically changed detent not works.

On my side, everything is fine now, and this issue can be closed :)

I already checked out your latest changes, which include namespaces. This commit fixed so many visual bugs. Big thanks.
