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

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. https://github.com/libratbag/libratbag/pull/1122 Co-developed-by: Filipe Laíns <lains@riseup.net> Signed-off-by: Filipe Laíns <lains@riseup.net> Signed-off-by: Mavroudis Chatzilazaridis <mavchatz@protonmail.com> Reviewed-by: Bastien Nocera <hadess@hadess.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
