pieeprom-2021-10-04: Add support for GPT FAT16 and increase USB timeouts - BETA

* Update the FAT detection to support FAT16 for EFI/ESD paritions with
  GPT instead of assuming FAT32. The latest firmware is also required
  for a similar update.
* Increase the timeouts for MSD SCSI commands to reduce the risk of
  timeouts when probing the capacity of slow to start devices
  e.g. USB RAID with spinning disks.
