This function allows you to make a deferred data-collection request, which will later be
executed, and the arguments validated, when you call ps3000aRunBlock in block mode.
The advantage of this function is that the driver makes contact with the scope only
once, when you call ps3000aRunBlock, compared with the two contacts that occur
when you use the conventional ps3000aRunBlock, ps3000aGetValues calling sequence.
This slightly reduces the dead time between successive captures in block mode.
After calling ps3000aRunBlock, you can optionally use ps3000aGetValues to request
further copies of the data. This might be required if you wish to display the data with
different data reduction settings.
