Fixes #1030.

State.wipe() called with no arguments now clears all keys, as the docs say, instead of raising TypeError on key not in None.

The script in the issue fails before this change and passes after it.

I checked this against main (36e3ff3) in a Linux container with Python 3.12.

• State({"a": 1, "b": 2}).wipe() raises TypeError: argument of type 'NoneType' is not iterable on main and returns {} with this change. wipe(keep=[...]), wipe(delete=[...]) and empty lists for either behave the same as before.
• tests/core/test_state.py: 26 passed.

Two things before merging:

1. The typing import in burr/core/state.py was rewrapped, which isn't part of the fix. Both black 23.11.0 and isort 5.12.0 with the settings in .pre-commit-config.yaml put it back on one line, so the pre-commit job will fail once CI runs here. Reverting that hunk is enough.
2. There is no test for the no-argument case. Something next to test_state_wipe_delete / test_state_wipe_keep would cover it:

def test_state_wipe_all():
    state = State({"foo": "bar", "baz": "qux"})
    wiped = state.wipe()
    assert wiped.get_all() == {}

Thanks for checking this.

1. Put the typing import in burr/core/state.py back on one line. That drops the hunk from the diff.
2. Added test_state_wipe_all to tests/core/test_state.py next to the other two wipe tests. It uses the test you suggested.
