Explore inefficiencies in cal_params.py

[lsetiawan]

There's a potential inefficiency in EK60 and EK80 'cw' data. See code below of where this might be.

echopype/echopype/calibrate/cal_params.py

Lines 291 to 297 in 3ca028f

	idxmin = np.abs(beam["transmit_duration_nominal"] - vend["pulse_length"]).idxmin(
	dim="pulse_length_bin"
	)
	# fill nan position with 0 (will remove before return)
	# and convert to int for indexing
	idxmin = idxmin.where(~transmit_isnull, 0).astype(int)
