[R-sig-Geo] release of RQGIS 1.0.0

["Jannes Münchow"]

Today we are proud to announce a major RQGIS release (already on CRAN). We have completely rewritten RQGIS now using the reticulate package to access the QGIS Python API. Overall, RQGIS is now even more user-friendly. Find more information on new features, what has changed and how to use RQGIS on following pages:
