 * Add logical meter formula for EV power.
 * A `MovingWindow` class has been added that consumes a data stream from a logical meter and updates an `OrderedRingBuffer`.

 ## Bug Fixes
 
 * Add COMPONENT_STATE_DISCHARGING as valid state for the inverter. DISCHARGING state was missing by mistake and this caused the power distributor to error out if the inverter is already discharging.
