Updating map to group by checkpoint number

[danielswaine]

The map needs updating to group checkpoints by number if the same checkpoint is used between challenges. If the checkpoint score differs between challenges, it must display the challenge time limit against the score. Currently, if two checkpoints are displayed, they will be on top of each other hiding the other marker.

e.g.

  "goals": [
    {
      "number": 1,
      "grid_reference": "8455-1790",
      "description": "Ea eos enim sed quod eaque aut.",
      "points_value": {
        "5 Hour": 10,
        "8 Hour": 20
      }
    },
    {
      "number": 2,
      "grid_reference": "9625-0015",
      "description": "Lacinia est sit amet, consequat lectus..",
      "points_value": {
        "5 Hour": 10
      }
    }
  ]

This is the data that is currently returned:
