GetAvailableRooms doesn't deserialise metadata correctly

[gioragutt]

When I set my room metadata, even at Client.cs:220 you can see that metadata is null in the received object.

  onInit(options: any): void {
    this.setState(this.initialPlayerState());
    this.maxClients = options.maxClients || MAX_PLAYERS_IN_ROOM;
    this.setMetadata({
      mode: options.mode || '',
      name: options.name || `Room ${this.roomId}`,
    });
  }

I tried JSON.stringifying the metadata object, still don't get a string on the client side.

As of 0.11.4, it is possible to retrieve the metadata from the client-side by defining a custom RoomAvailable + Metadata types.

Example:

[Serializable]
class Metadata
{
	public string mode;
	public string name;
}

[Serializable]
class CustomRoomAvailable : RoomAvailable
{
	public Metadata metadata;
}

var roomsAvailable = await client.GetAvailableRooms<CustomRoomAvailable>(roomName);

for (var i = 0; i < roomsAvailable.Length; i++)
{
    // getting metadata
    Debug.Log("metadata.mode: " + roomsAvailable[i].metadata.mode);
    Debug.Log("metadata.name: " + roomsAvailable[i].metadata.name);
}

The metadata comes from a JSON response from the server. Unfortunately, the built-in JsonUtility from Unity has limitations regarding the usage of generic types, making it necessary to create a new type having its own hardcoded Metadata type defined on it. (here's the method to decode the JSON response)

If you think the API can be improved please don't hesitate to share your thoughts.
