Description:
This pull request introduces support for serializing a pandas DataFrame objects within the JsonPlus serializer. The changes include:
Extending the msgpack default serialization function to check if an object is a pandas DataFrame. If so, the DataFrame is converted to a dictionary using its to_dict() method, then wrapped in a msgpack ExtType with a unique extension code.
Leveraging the existing deserialization logic (EXT_CONSTRUCTOR_POS_ARGS) to reconstruct the DataFrame from the serialized dictionary.
Enabling modules like MemorySaver to store DataFrame objects directly using the new serialization support, allowing for seamless saving and retrieval of DataFrames without additional modifications.
