Add manual open/close functionality to LOConnection component

There is currently not a way to tell `lo_modules.LOConnection` to open or close. Currently, the functionality is handled in on initialization and when the `data_scope` value changes. We ought to have some property that can be called to manually open or close the socket.

Likely best to create new props and check if they changed in `componentDidUpdate`.

Update 10/28/24:
We are slowly transitioning away from Dash in Python toward using NextJS instead. We have a new LO Connection component in `lo_event/lo_assess/LOConnection` (#180) which should use this feature instead.

Start with the existing lo_modules.LOConnection component and its data_scope update handling, then compare it with lo_event/lo_assess/LOConnection from issue #180. Confirm how the component is initialized and updated; done means the newer LO Connection component supports manually opening and closing its socket.
