feat(protocol/hytale): add support for Hytale servers (#750)

Add protocol implementation for querying Hytale game servers using
the Nitrado Query API endpoint. The protocol uses HTTPS with HTTP
fallback to fetch server information including name, version, player
count, and map.

Example:
  $ gamedig --type hytale play.hyfyve.net:5523

  {
    "name": "Hytale Server",
    "map": "default",
    "version": "2026.01.13-dcad8778f",
    "maxplayers": 100,
    "numplayers": 1,
    "connect": "play.hyfyve.net:5523"
  }
