HID: logitech-dj: Add support for a new lightspeed receiver iteration

Browse Source 
The lightspeed receiver for the Pro X Superlight uses 13 byte mouse reports
without a report id. The workaround for such cases has been adjusted to
handle these larger packets.

The device now reports the status of its battery in wireless mode and
libratbag now recognizes the device and it can be configured with Piper.
