Added an accessor to PendingEvent to be able to get back typed data

Added an accessor to PendingEvent to be able to get back typed data, instead of just a JsonElement.

It's not fully populated and someone with some more knowledge about the events and their data would be able to better fill it out, but I think it's a great start and can easily be expanded upon.

I.e.

Now you can do the following:

foreach (var edge in response.Result.Data.Result.Edges)
{
    if (edge.Node.DataTyped is PendingEventDataTransfer eventDataTransfer)
    {
        Console.WriteLine($"From: {eventDataTransfer.From}");
        Console.WriteLine($"To: {eventDataTransfer.To}");
        Console.WriteLine($"Amount: {eventDataTransfer.Amount}");
    }
}

Instead of:

foreach (var edge in response.Result.Data.Result.Edges)
{
    var root = edge.Node.Data.Value;
    if (root.ValueKind == JsonValueKind.Object)
    {
        foreach (JsonProperty prop in root.EnumerateObject())
        {
            Console.WriteLine($"Key: {prop.Name}, Value: {prop.Value}");
        }
    }
}

Looks good :) Would you mind going through and adding some summary blocks for the properties? Just to keep everything consistent. Cheers!

@v16Studios I've added some, although I had to guess what their purpose was, since I don't actually know. Some of the events I added, I just did so because I saw their data in the returned data from the call.

Like I said, it's also incomplete, I'm not sure what other events are possible, or even what all of their properties mean.

For example, I'm not sure what the Deposit or Withdraw events are actually for, I just made an assumption about what the properties might be.
