Python 3.11 dataclass compatibility

[tboquet]

Hi, Using python 3.11 @dataclass decorator throws an error. Here is the traceback

    import tasknet as tn
/venv/lib/python3.11/site-packages/tasknet/__init__.py:1: in <module>
    from .models import *
/venv/lib/python3.11/site-packages/tasknet/models.py:23: in <module>
    from .tasks import Classification
/venv/lib/python3.11/site-packages/tasknet/tasks.py:198: in <module>
    @dataclass
/usr/local/lib/python3.11/dataclasses.py:1230: in dataclass
    return wrap(cls)
/usr/local/lib/python3.11/dataclasses.py:1220: in wrap
    return _process_class(cls, init, repr, eq, order, unsafe_hash,
/usr/local/lib/python3.11/dataclasses.py:958: in _process_class
    cls_fields.append(_get_field(cls, name, type, kw_only))
/usr/local/lib/python3.11/dataclasses.py:815: in _get_field
    raise ValueError(f'mutable default {type(f.default)} for field '
E   ValueError: mutable default <class 'tasknet.tasks.DataCollatorForMultipleChoice'> for field data_collator is not allowed: use default_factory

It looks like a field would be needed here.
