Incorrect documentation: `name` is not an optional argument to `define_keymap`

Great project, have tried for 4 days solid trying to remap keys in linux, this has been the only reliable solution for me, well done!

The documentation says:

Argument name specifies the keymap name. This is an optional argument.

However this code:

from xkeysnail.transform import Key, define_keymap

define_keymap(None, {
    Key.CAPSLOCK:  Key.LEFT_META,
    Key.LEFT_META: Key.ESC,
    Key.ESC : Key.CAPSLOCK,
}, None)  # <-- Name is None here

Results in this error:

  File "/usr/local/lib/python3.10/dist-packages/xkeysnail/transform.py", line 457, in transform_key
    print("WM_CLASS '{}' | active keymaps = [{}]".format(wm_class, ", ".join(keymap_names)))
TypeError: sequence item 0: expected str instance, NoneType found

However adding a name makes it work fine:

from xkeysnail.transform import Key, define_keymap
define_keymap(None, {
    Key.CAPSLOCK:  Key.LEFT_META,
    Key.LEFT_META: Key.ESC,
    Key.ESC : Key.CAPSLOCK,
}, "Michael") # <-- Name is set here
