changed all ind returned by band names as character, instead of band numbers
Finished feature implementation; no validation yet
Tiny bug fix, package builds and loads now.
Validation of tiff feature successful on 2 datasets. One hdf ordered on earth explorer only containing the sr bands and a geotiff (usgs test datasets), containing the already pre-processed Indices. IMO the filenames structure will change a little and I may have to adapt some regex when tiff become available via earthexplorer order
Merge branch 'feature-tiff' into develop
