Simplify Core State

[dostuffthatmatters]

Right now, we have two states (the persistent one and the temporary one). It would be way cleaner to just have one state and null everything temporary on the startup of the core.

Additionally, the way how partial updates are done is very complicated. We can use a contextmanager:

# old way:

def apply_state_update(state: types.PyraCoreState ) -> types.PyraCoreState:
    state.enclosure_pc_readings.actors.current_angle = new_cover_angle
    state.enclosure_pc_readings.state. cover_closed = new_cover_angle == 0
    return state

interfaces.StateInterface.update_state(apply_state_update)


# new way:

with interfaces.StateInterface-update_state_in_context) as state:
    state.plc_state.cover_angle = new_cover_ angle
    state.plc_state. cover_closed = new_cover_angle == 0
