IGroBufCustomSerializer implementation for <object>and <dynamic>

[halittiryaki]

Is it possible to provide a custom serializer for objects of type object and dynamic?
It seems objects of those types gets ignored by ignoreCustomSerialization.

able to workaround this problem with additional members having the actual type defined:

  public dynamic dynVal { get; private set; }
  public object objVal;

  public ExpandoObject DynValFix { get => dynVal as ExpandoObject; set => dynVal = value as ExpandoObject; }
  public ExpandoObject ObjValFix { get => objVal as ExpandoObject; set => objVal = value as ExpandoObject; }
