Changed

• Serializer can now be extended with custom struct encoding policy.
• Improved error types and its messages for serialization part.
  • New error type introduced - UnknownLength. Returned on attempt to serialize struct, map or serquence with unknown
    length (Serde allows this).
  • The new type is returned if necessary.

Fixed

• Deserializer now properly works with enums.
• Options with default values (that can be initialized using unit marker) deserialization.
  This fix also forbids the following Option deserialization cases:
  • Option<()>.
  • Option<Option<...>>.
    It's impossible to properly deserialize the listed cases without explicit option marker in protocol.
• Serializer now properly serializes unit structs.
  Previously it was serialized as a unit (nil), now there is just an empty array ([]).
