Add an option to ignore ordering in arrays

[yanns]

When comparing two jsons, it'd be nice to have the option to ignore ordering in arrays.

["a", "b"]

would be considered the same as

["b", "a"]

My more concrete example is:

{
  "ApprovalFlowCreated" : {
    "fields" : [
      { "name" : "approvalFlow" },
      { "name" : "type" }
    ]
  }
}

should be considered the same as:

{
  "ApprovalFlowCreated" : {
    "fields" : [
      { "name" : "type" },
      { "name" : "approvalFlow" }
    ]
  }
}
