Implement deserialization of list of changes in Transaction response converter

[kPatch]

Parse through list of event changes from transaction response.
Below is the outline of the code.

TransactionConverter.cs

if (item["changes"] != null)
{
List<Change> changes = new List<Change>();

// TODO: Complete TransactionConverter deserialization of Changes array
JArray jChanges = new JArray(item["changes"]);
foreach (var change in jChanges)
{
    // TODO: onChage
    //JObject oChange = change.ToObject<JObject>();
    //string typeStr = oChange["type"].ToString();

    //if (typeStr.Equals("write_resource"))
    //{
    //    ChangeWriteResource changeWResource = new ChangeWriteResource();
    //    changeWResource.Type = (string)change["type"];
    //    changeWResource.StateKeyHash = (string)change["state_key_hash"];
    //    changeWResource.Address = (string)change["Address"];

    //    changes.Add(changeWResource);
    //}
    //else if (change["type"].Equals("write_table_item"))
    //{
    //    ChangeWriteResourceWriteTableItem changeWRWRT = new ChangeWriteResourceWriteTableItem();
    //    changeWRWRT.Type = (string)change["type"];
    //    changeWRWRT.StateKeyHash = (string)change["state_key_hash"];
    //    changeWRWRT.Handle = (string)change["handle"];
    //    changeWRWRT.Key = (string)change["key"];
    //    changeWRWRT.Value = (string)change["value"];
    //    changeWRWRT.Data = (string)change["data"];

    //    changes.Add(changeWRWRT);
    //}
}

transaction.Changes = changes.ToArray();
}
