Unclear error `File.create` different `n_tx` across fields

[wesselvannierop]

In field 'scan': Dimension 'n_tx' has inconsistent sizes across fields ['azimuth_angles', 'center_frequency', 'demodulation_frequency', 'focus_distances', 'initial_times', 'polar_angles', 't0_delays', 'time_to_next_transmit', 'transmit_origins', 'tx_apodizations']: [1, 149]
  File "<string>", line 18, in __init__

Maybe we can log the n_tx for every field to spot the outlier easily.

I have a fix for this, but waiting for #392 to be merged
