Mock device websocket for storybook

[SeijDeLeon]

Various beamline device controller components and live plot monitors rely on ophyd websocket for functionality. If we put the components in storybook without a mock device then there is no functionality and it will default to a 'device not connected' view.

Add a custom hook that recreates the functionality of useOphydSocket with pure js so components can be instantiated with it and then rendered to storybook.

Added a couple mock hooks in #34 however they are not very sophisticated and we should still create something a little more sophisticated which could also potentially be used for testing

Developments from @Prinstar have mostly resolved this with the addition of ophyd-sim, the next step is to utilize ophyd-sim inside of storybook and get the controls components added.
