### Feature Request / Improvement Right now, various classes in PyIceberg cannot be pickled. This is due `__new__` lacking a corresponding `__getnewargs__` in various places ([pickle docs](https://docs.python.org/3/library/pickle.html#object.__getnewargs__)). Pickle support is required by, e.g., Dask to serialise tasks as they are distributed to workers. Here is a simple example: ```python import pickle from pyiceberg.expressions import And, EqualTo ex = And(EqualTo('name', 'test'), EqualTo('value', 0)) pickle.loads(pickle.dumps(ex)) ``` This results in the following exception: ``` Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: And.__new__() missing 2 required positional arguments: 'left' and 'right' ``` I'm happy to provide a fix, but I'd like to hear your thoughts first. ### Query engine Other -- This is an automated message from the Apache Git Service.
