dms: new 'Foxconn Set FCC authentication' command

Due to an influx of spam, we have had to impose restrictions on new accounts. Please see this wiki page for instructions on how to get full permissions. Sorry for the inconvenience.
This command allows unlocking Foxconn-manufactured modules like the Dell-branded DW5821e (T77W968) or the new 5G-capable T99W175 module shipped in Lenovo Thinkpads. Without the unlock, the module cannot be put online (RF is kept off).
The command was found looking at a USB capture obtained from running the "Dell Custkit tool for the DW5821e/DW5829e" under Windows: 0x01, 0x10, 0x00, 0x00, 0x02, 0x01, 0x00, 0x01, 0x00, 0x71, 0x55, 0x04, 0x00, 0x01, 0x01, 0x00, 0x00
