Add sortBy and reverse functions

[kit494way]

Is your feature request related to a problem? Please describe.
I want to sort list of objects by key.
And, I want to reverse list.

Describe the solution you'd like
sortBy:

echo '[
    {
      "id": 1,
      "updatedAt": "2024-09-04T00:00:00+09:00"
    },
    {
      "id": 2,
      "updatedAt": "2024-09-03T00:00:00+09:00"
    }
  ]' | dasel -r json 'sortBy(updatedAt)'
[
  {
    "id": 2,
    "updatedAt": "2024-09-03T00:00:00+09:00"
  },
  {
    "id": 1,
    "updatedAt": "2024-09-04T00:00:00+09:00"
  }
]

reverse:

echo '[
    {
      "id": 1,
      "updatedAt": "2024-09-04T00:00:00+09:00"
    },
    {
      "id": 2,
      "updatedAt": "2024-09-03T00:00:00+09:00"
    }
  ]' | dasel -r json 'reverse()'
[
  {
    "id": 2,
    "updatedAt": "2024-09-03T00:00:00+09:00"
  },
  {
    "id": 1,
    "updatedAt": "2024-09-04T00:00:00+09:00"
  }
]
