Paginated `Data*`-type models don't contain pagination info

[mirrorcult]

Changing pagination options is still possible, I just didnt think this would be useful. SRC API says it looks like this (https://github.com/speedruncomorg/api/blob/master/version1/pagination.md):

{
  "data": [<etc>, <etc>, <etc>],
  "pagination": {
    "offset": 20,
    "max": 30,
    "size": 30,
    "links": [{
      "rel": "next",
      "uri": "https://www.speedrun.com/api/v1/[etc]?max=30&offset=50"
    }, {
      "rel": "prev",
      "uri": "https://www.speedrun.com/api/v1/[etc]?max=30"
    }]
  }
}
