- function `check_gdal()` was rewritten in order not to use package gdalUtils;
- functions `gdal_wap()` and `gdalwarp_grid()` were modified for the same purpose;
- support for MacOS was added.

 This version allows to perform all basic operations with Sentinel-2 data: finding and downloading the required tiles (on Linux), correcting them with sen2cor, processing them (merging adiacent tiles, clipping, reprojecting, rescaling, applying atmospheric mask) to create output multiband files (in a format managed by GDAL) and spectral indices.
