This PR adds the ability to optionally taper the Leith+E backscatter coefficient as a function of depth. It is controlled by three parameters:
TAPER_LEITHY: If true, the Leith+E backscatter coefficient is tapered as a function of depth. Default False.LEITHY_DEPTH: Above this depth Leith+E is not modified.LEITHY_WIDTH: Between depths ofLEITHY_DEPTHandLEITHY_DEPTH + LEITHY_WIDTHthe backscatter coefficient is tapered by a smooth cubic function of depth. The backscatter coefficient is set to zero belowLEITHY_DEPTH + LEITHY_WIDTH.
