Unsupported C# types

[guyilin-amazon]

The ObjectMapper doesn't support serialize/deserialize char C# type currently. The property or field that has char type will be serialized to an empty Ion struct, and will be deserialized as the default char value which is '\0' (U+0000).

[guyilin-amazon]

Besides char type, other C# types that are not included in The Ion/.NET type mapping table are not supported either. For example, integral types byte, sbyte, short, ushort, uint, ulong, nuint, nint are not supported currently.
