Follow-me stair light for the Apollo MTR-1 and WLED

ESPHome package for the Apollo MTR-1: tracks people on the stairs with the
LD2450 radar and streams a lit window to a WLED controller over DDP. The
sensor serves a setup wizard that measures the stairs with one walk and
stores the setup on the device.
