What is the Expected Behaviour?

More Information

In Python 3.14 the output of the help produced by argparse is changed, causing 3 esptool tests to fail.
In tests, there's expected: 'usage: __main__.py [-h]', and actual: usage: python3 -m espefuse [-h], see: https://docs.python.org/dev/whatsnew/3.14.html#argparse

Failed tests:
FAILED test/test_espefuse.py::TestReadCommands::test_help
FAILED test/test_espefuse.py::TestReadCommands::test_help2
FAILED test/test_espefuse.py::TestMultipleCommands::test_multiple_cmds_help
