    Made the 'field' parameter case-insensitive, as specified by the protocol.
    
    The protocol document states that field names are case-insensitive, but
    prior to this commit, the server implementation was non-compliant:
    
      % for field in as_number AS_Number; do
      %   curl -s "https://onionoo.torproject.org/details?limit=1&fields=$field"
      % done | jq .relays[]
      {
        "as_number": "AS24940"
      }
      {}
    
    This bug accidentally discovered during performance analysis, using
    <https://gist.github.com/fmap/6f44efe6f3ca3f79683b>.
