[Bug]: Strings over RPC fail to be parsed

[N3X15]

Steps to reproduce

// Note: This file doesn't actually need to exist.
namespace Your.RPC
{
    public static class Class
        /// <summary>
        /// Test method
        /// </summary>
        /// <param name="aString"></param>
        [Preserve]
        public static void AMethodThatAcceptsASingleString(string aString)
        {
            // Will never make it here.
            AssertIsDevBuild();
            Debug.Log("SUCCESS");
        }
    }
}

from gamium import *

service = TcpGamiumService("127.0.0.1", 50061)
gamium = GamiumClient(service)

gamium.connect()

# Send any non-numeric string over RPC
gamium.execute_rpc(
    RpcBy.method(
        "Your.RPC.Class",
        "AMethodThatAcceptsASingleString",
        "c11557d5-ffcc-47fc-9263-2b1717eb070d",
    )
)

Expected result

Client successfully sends the request and prints out SUCCESS in console.

Actual result

Client crashes prior to sending request to server.

Use-case: Our testing process requires that we send GUIDs over RPC for loading worlds, since actually browsing for the world in UI is currently an overly-complicated task for automation.

WORKAROUND: Sending a Dict[str, Any] seems to work fine:

# Send any GUID over RPC
gamium.execute_rpc(
    RpcBy.method(
        "Your.RPC.Class",
        "AMethodThatAcceptsAJSONObject",
        {"guid": "c11557d5-ffcc-47fc-9263-2b1717eb070d"},
    )
)

You will, however, need to change your method signature:

        /// <summary>
        /// Test method
        /// </summary>
        [Preserve]
        public static void AMethodThatAcceptsAJSONObject(JObject json)
        {
            var guid = (string)json["guid"];
            Debug.Log("AMethodThatAcceptsAJSONObject: "+guid);
        }

The problematic code has been fixed, but deploy will be delayed due to PyPI account issues.

Fixed in version 2.0.10.
