v1.80.0

-- Redo Export Snirf feature for Exporting derived data to SNIRF file.
-- Add SnirfClass functionality to plot derived data.
-- Fix Spline SG MakeFilter.m with Teresa Girolamo  Group dataset. The message for her data set keeps displaying the warning "Filter parameters exceed Nyquist frequency" during processing that ties up user clicking OK to message box messages for each channel of data time series.  Fix by instead displaying a message dialog once for each file or option to quit processing and throw error exception.
-- Fix issue with menu threowing exception error

   Error using matlab.ui.Figure/set
   Error setting property 'Position' of class 'Figure':
   Width and height must be greater than or equal to 0

because we change parent units for screen to 'normalized'. Fix is to make sure to always set the monitor units back to 'pixels'.
