Everything`s look fine, just number calculation for buffer size as Azra pointed out in "projects/UltraSound/extra/ultrasonic_distance_acq_detailed_dataset/ultrasonic_distance_acq_detailed_dataset.ino" and "projects/UltraSound/ultrasonic_distance_acq/ultrasonic_distance_acq.ino"

Does this PR introduce a breaking change?
N/A
Other information
SensEdu_ADC_Buffer and SensEdu_DAC_Buffer both are using MPU config now, so it doesn't matter which one to use.
There is a new macro SensEdu_DMA_Buffer which is preferable to use to reflect the identical buffer logic.
