FIX - s1 recipe should allow to set the band name in ingredients file

[Bang Pham Huu]

For example systemtest/30-wcstimport/testdata/023-sentinel1_GRD_custom_recipe

    "name": "sentinel1",

It should allow to specify band name like with other general recipe, so it will not be always Grey after importing to petascope.

{         "slicer": {
          "type": "gdal",
          "bands": [
            {
              "name": "red",
              "identifier": "red"
            }
          ]
          
 }
