New demeter file on /pic/projects/im3/teleconnections/data/land/usa_demeter.csv which only has points in the USA and is converted to meters too look at area. Two functions are added, one to load up demeter file and the other to count the irrigated crops. Irrigation status is determined by comparing the area of irrigated crops to the area of rain-fed crops. If irrigated crop area is larger, it is counted as an irrigated crop. This resolves #25
