python: MultiUSRP: Fix send_waveforms()
The send_waveform() function takes the waveform_proto array and if it
has only 1 channel, explicitly reshapes it to be
(1, waveform_proto.size), or uses np.tile to replicate the
waveform_proto array over X channels. It then proceeds to loop over the
waveform_proto array, but attempts to do so over the channel dimension
instead of looping over the actual samples. This results in sending the
entire waveform_proto array regardless of the duration specified.
The fix is to specify the dimension in which it crops, and not crop in
dimension of the channels.
