Independent color parameter controls give inconsistent results if websocket updates are slow

[SpComb]

For a head with RGB color controls, each of the RGB controls has its own independent component value. When each of those controls update, they use the most recent color parameter values updated by the server, not the values set by the other control components.

That means that adjusting two color controls will give the wrong color if the websocket does not update in between.

Fixed to keep local color state in the ColorControlComponent on changes, but that means that any external color updates from websocket events are ignored until the component is reloaded.
