Wallpapper Versions Save

New console application can be used to generate JSON file with Sun location based on EXIF metadata from photos. For example:

$ wallpaper-exif 1.jpeg 2.jpeg 3.jpeg 4.jpeg

When in JSON file there is no information about static light/dark pictures, then information about static appearance is not added to output file. Thus JSON like that can be used:

[
  {
    "fileName": "1.png",
    "isPrimary": true,
    "altitude": 27.95,
    "azimuth": 279.66
  },
  {
    "fileName": "2.png",
    "altitude": -31.05,
    "azimuth": 4.16
  },
  {
    "fileName": "3.png",
    "altitude": -26.10,
    "azimuth": 27.03
  },
  {
    "fileName": "4.png",
    "altitude": -15.23,
    "azimuth": 45.83
  },
  {
    "fileName": "5.png",
    "altitude": 0.05,
    "azimuth": 60.58
  },
  {
    "fileName": "6.png",
    "altitude": 16.31,
    "azimuth": 72.80
  },
  {
    "fileName": "7.png",
    "altitude": 34.16,
    "azimuth": 84.31
  },
  {
    "fileName": "8.png",
    "altitude": 52.38,
    "azimuth": 97.87
  },
  {
    "fileName": "9.png",
    "altitude": 69.59,
    "azimuth": 122.59
  },
  {
    "fileName": "10.png",
    "altitude": 77.09,
    "azimuth": 196.03
  },
  {
    "fileName": "10.png",
    "altitude": 64.00,
    "azimuth": 248.53
  },
  {
    "fileName": "10.png",
    "altitude": 46.15,
    "azimuth": 267.27
  },
  {
    "fileName": "10.png",
    "altitude": 10.41,
    "azimuth": 291.18
  },
  {
    "fileName": "14.png",
    "altitude": -5.95,
    "azimuth": 304.07
  },
  {
    "fileName": "15.png",
    "altitude": -19.51,
    "azimuth": 320.06
  },
  {
    "fileName": "16.png",
    "altitude": -28.63,
    "azimuth": 340.41
  }
]

Now single file can be added to multiple nodes (it's encoded only once in HEIC file).

Fix issue with value of index for time wallpapers.
