extract bluetooth firmware from window driver files

With this script:
python3 extract-ibt-fw.py [--verify] BT_21.10.1_64_Win8.1.exe [output-dir]
you can extract the firmware binary and use it on Linux.

The script als0 checks if the SHA-sum of the extract file matches the expected
one.

You also need the Windows driver files. Intel doesn't provide a public download
link anymore. 

The Firmware is in this file: 
BT_21.10.1_64_Win8.1.exe
