ranghetti/sen2r: Version 1.3.4

New functions

• gdalUtil(): function used to perform GDAL operations, calling C-based GDAL utilities using sf::gdal_utils(), and Python-based ones through system calls (a standalone GDAL environment is request to do it, as it was in previous versions).

• Improve documentation of vignette "Output file structure", including the description of output products.

• rgdal is now an explicit dependency (this because it is used by raster but it is not a mandatory dependency).

• GDAL C-based utilities are called using internal GDAL routines in package sf (see gdalUtil()). This allows reducing the use of external runtime dependencies.
• GDAL messages are suppressed if the suggested dependency sys is installed (#257).
• The new section of the vignette "Output file documentation" regarding products is linked in the GUI.

• Re-fix #292.
• Fix #308.
