Proxy methods (override or add) do not support parameters

[IFYates]

Describe the bug
Adding a proxy methods (override or add) with any parameters after the instance will fail to shim.

Reproducible Example

public class TestClass {
    ...
}

public interface IShim {
    [ShimProxy(typeof(ProxyLogic))] // Add or Override gives same result
    string Method(string arg);
}

public class ProxyLogic {
    public string Method(IShim inst, string arg) {
        return $"[{arg}]";
    }
}

var shim = new TestClass().Shim<IShim>(); // Currently throws exception
var res = shim.Method("test");

Expected behaviour
res should be [test]

Actual behaviour
Exception is thrown.
