FIX - matching input files to areasOfValidity elements implicitly

[Bang Pham Huu]

in areasOfValidity it can contain a list of elements, and wcst_import can match each input file to the corresponding areasOfValidity element, by each slice's min and max see:

"min": "datetime(regex_extract('${file:name}', 'DLT_(....)_.*', 1), 'YYYY')"

and areasOfValidity's start and end.

Example:

    "tmp_directory": "/tmp/",

                }
              ]
            },
            "X": {

              "resolution": "${gdal:resolutionX}"
            },
            "Y": {

          }
        }
      },

    }
  }

Also, wcst_import needs to validate that the datetime of min should be between the start and end of areasOfValidity.

For example, min points to "2018" which is resolved as 2018-01-01T00:00:00.000Z and it does not exist between "2018-03-01T00:00:00.000Z":"2008-12-31T23:59:59.999Z":

          "axes": {
            "time": {
              "min": "datetime(regex_extract('${file:path}', '.*/base/(....)/.*', 1), 'YYYY')",
              "irregular": true,
              "dataBound": false,
              "areasOfValidity": [
                {
                  "start": "2018-03",
                  "end": "2018-10"
                }
              ]
            },

and if min value of X/Y axes are wrong like below

 "X": {
              "min": "2018-03",
              "max": "${gdal:maxX}",
              "resolution": "${gdal:resolutionX}"
            },
            "Y": {
              "min": "2018-03",
              "max": "${gdal:maxY}",
              "resolution": "${gdal:resolutionY}"
            }

then wcst_import should throw proper exception instead
