Interpolates LAI into daily values

Description

This function generates a continuous series of LAI from downloaded from the lpdaac AppEEARS download portal. This is done through the phenofit R package https://github.com/kongdd/phenofit. A rough fit is done using a weighted Whittaker smoother and then curve fitting is done using an assymetric Gaussian function.
