"fasterRaster": Faster raster and spatial vector processing using "GRASS GIS"

Description

fasterRaster: Processing of large-in-memory/-on disk rasters and spatial vectors in using GRASS GIS. Most functions in the terra and sf packages are recreated. Processing of medium-sized and smaller spatial objects will nearly always be faster using terra or sf. To use most of the functions you must have the stand-alone version of GRASS GIS version 8.3 or higher (not the OSGeoW4 installer version). Note that due to differences in how GRASS, terra, and sf were implemented, results will not always be strictly comparable between functions for the same operation.
