Add LightEffect module for smart light strips (#918)

Implements the `light_strip_lighting_effect` components for
`smart` devices. Uses a new list of effects captured from a L900 which
are similar to the `iot` effects but include some additional properties
and a few extra effects.

Assumes that a device only implements `light_strip_lighting_effect` or
`light_effect` but not both.
