Replace StateConnection Implementation

[StevenLambion]

This PR removes the old state connection implementation for a simpler, reference-free one. The old implementation allows the state to be sliced up between views, but it requires an implementation that isn't SwiftUI friendly. It also adds complexity for a feature that isn't used in my own project and has been removed from the documentation of this libray.

Work Performed

• Removed StateConnection
• Refactored the Connector view to map the state to the ConnectableView's props.
• Added StoreWrapper to inject the Store<_> object into the environment.
• Removed storeUpdated environment value.
