This is work in progress since it should probably not be merged before its used for anything

This now has support for enabling and disabling trigger holdoff on the 3260 card. The following
code illustrates the problem. Triggering at ~200 KHz on a 20 MHz sine signal from a function generator with a trigger pulse per cycle.

@jenshnielsen thanks for looking into it! Perhaps, this information can be copy-pasted and pushed to the Reports repo?

[jenshnielsen]

@QCoDeS/core I think this is ready for review the report is up at QCoDeS/Reports#7

The firmware needed has been released officially yesterday

[astafan8]

Great addition! I'll add it to 9373 when i'll be working on a driver for it
