Siglent SDS2000X plus hack

@KollerJulian check the EEVblog forum: https://www.eevblog.com/forum/index.php. That's where I found the code above.

the script lacks some options, you can update it like this
bwopt = ('25M', '40M', '50M', '60M', '70M', '100M', '120M','150M', '200M', '250M', '300M', '350M', '500M', '750M', '1000M', 'MAX', 'AWG', 'WIFI', 'MSO', 'FLX', 'CFD', 'I2S', '1553', 'PWA','MANC', 'SENT')

There's a new option for SDS2000X Plus, fw 1.6.2R5: ARINC.

Adding 'A429' to the bwopt variable in the script gives the correct key.
