Python version
3.10

Django version
4.1

Package version
0.16.3.

Current behavior (bug description)
When MAINTENANCE_MODE_STATE_FILE_PATH is defined using pathlib.Path (as suggested by the default Django settings file), e.g.:

MAINTENANCE_MODE_STATE_FILE_PATH = BASE_DIR.parent / "maintenance_mode_state.txt"

AttributeError is raised with message with message 'PosixPath' object has no attribute 'decode'.

Expected behavior
It would be nice to define the path using pathlib.Path as well.
