Make major changes to the read_ERA_wind.m function to perform similar functions to get_NCEP_forcing.m. The function now reads in a lot of data for a model domain and extracts only the times which fall within the given period
Remove the old code which was outside the loop to read in a series of files. Also fix the way the try/catch statements were being used to get either the ggas or the gafs variables. Fix the way the times are calculated to account for the fact that the file names can use either of two systems (time_origin + offset or 24 hour time)
