Added pre- and post-sampling dependent on ADC dead time

[schote]

So far, the console does not sample data during ADC delay and dead time. The dead time symmetrically adds time at the beginning and the end of an ADC event, but the ADC gate signal is off during that time.

This PR changes the interpretation of the ADC dead time in the sense, that the dead time is now considered as sampling time. The number of extra samples acquired before and after the true ADC event is stored in RxData.
Note that the dead time samples are added as a multiple of the adc dwell time defined in an ADC block:

num_samples_discard = round(dead_time / adc_dwell_time)
...
total_gate_duration = (num_samples + 2*num_samples_discard) * adc_dwell_time

This means:

• If the adc dead time is smaller than the adc dwell time, the dead time does not contribute to the sampling time and is symmetrically distributed around the ADC gate
• If the adc dead time is a multiple of the adc dwell time, the dead time symmetrically adds samples to the adc gate, no left over
• If the adc dead time is > adc dwell time but not a multiple, the dead time symmetrically adds samples and the "left-over" time is at the end of the adc block

The RxData instance of an ADC event keeps all the acquired samples (in the unprocessed data and in the processed data) so the truncation of pre and post samples needs to be done by post-processing.

The number of pre and post samples to be discarded is written to the acquisition header of the generated ISMRMRD file, to be considered during reconstruction.
