Fix for Sentinal2_crop_growing_conditions

[leonard-psu]

Notebook requires slight modification to work.
Also requires docker changes to install gdal.

   collection: str = 'sentinel2'
    
    # set up mapping configs
    mapper_configs = MapperConfigs(
        #collection='sentinel2-msi',
        collection=collection,
        time_start=time_start,
        time_end=time_end,
        feature=feature,
        metadata_filters=metadata_filters
    )
 #get a new mapper instance. Set sensor to `sentinel2`
# mapper = Mapper(mapper_configs, sensor='sentinel2')
    mapper = Mapper(mapper_configs)

Hi @leonard-psu thanks for spotting this - could you open an PR and propose the changes directly in the code?

You might actually combine #17 and this issue into a single PR btw...
