Release 1.1 - move to terra

The FOTO (Fourier Transform Textural Ordination) method uses a principal component analysis (PCA) on radially averaged 2D Fourier spectra to characterize (grayscale) image texture.

• Updating from {raster} to {terra} to address the removal of {rgdal}

an R implementation of the "fourier transform textural ordination (foto)" method
