lazysf: Delayed Read for 'GDAL' Vector Data Sources

Lazy read for drawings. A 'dplyr' back end for data sources supported by 'GDAL' vector drivers, that allows working with local or remote sources as if they are in-memory data frames. Basic features work with any drawing format ('GDAL vector data source') supported by the 'gdalraster' package.
