Blocking Operation of Single Shot Measurement Now Optional

[ab-tools]

Hello,

it is very inconvenient that this library enforces a 5 sec. blocking delay when performing a single shot measurement.

It is understood that you need to wait for 5 sec. till the measurement results are available, but this can be done in the calling application in a non-blocking fashion.

I've therefore added a parameter which allows non-blocking operation of the single shot measurement method with blocking mode being the default - so no behavior change for existent applications.

Best regards
Andreas

I agree, blocking for 5 seconds is way to long. There should be a non-blocking option as well.
Thanks a lot for your contribution.
