Supported test fails

[Evert0x]

This assertion throws an error when running the unit tests: https://github.com/hatching/sflock/blob/master/tests/test_main.py#L30

`> assert count == len(supported())
E AssertionError: assert 14 == 15
E + where 15 = len([b'.msg', b'.7z', b'.iso', b'.gzip', b'.lzh', b'.lha', ...])
E + where [b'.msg', b'.7z', b'.iso', b'.gzip', b'.lzh', b'.lha', ...] = supported()

tests/test_main.py:30: AssertionError`

The full string of supported() is: [b'.msg', b'.7z', b'.iso', b'.gzip', b'.lzh', b'.lha', b'.daa', b'.eml', b'.bup', b'.zip', b'.mso', b'.tar', b'.tar.gz', b'.tar.bz2', b'.pdf']
