Three to four-byte conversion

data_out.dtype = np.byte
data_out = data_out.reshape(-1, 4) # Shape is now (128,4) and dtype is byte
# Now, copy the data from chans08to00 into data_out. We need to specify which bytes to put it in.
# Also, we need to reverse the data in frame.
# You'd change 0:3 to 1:4 if the stuff in frame is big-endian, I think? You'll need to experiment.
