We cannot pickle FileIO implementations currently due to the file system initialization being inside a LruCache wrapper instance.
For example if one tries to pickle.dumps(pyarowfileIO) now they will encounter the following error.
This change implements getstate and setstate on PyArrowFileIO and FsSpecFileIO so that they can be pickled
