Add option to download only certain layers.
Add data_year argument to support new dataset versions.
Misc doc and CRAN check fixes.
Fix output as GeoTIFF with LZW compression. Smaller file sizes are advantageous when analyzing large areas.
Upgrade to roxygen2 > 4.0.2
Switch to gConvexHull in calc_gfc_tiles to avoid potential errors from gUnaryUnion.
Move "snow" from Suggests to Enhances
Update inst/examples/analyze_GFC.R to test or "snow"
