Example usage invocation appears incorrect

When I run python3 -m cppcheck-codequality --input-file=cppcheck_out.xml --output-file=cppcheck.json I get:

/path/to/project/pyvenv/bin/python3: No module named cppcheck-codequality

Replacing it with python3 -m cppcheck_codequality --input-file=cppcheck_out.xml --output-file=cppcheck.json (note the underscore to match the package name) I get:

/path/to/project/pyvenv/bin/python3: No module named cppcheck_codequality.__main__; 'cppcheck_codequality' is a package and cannot be directly executed

However, you correctly establish an entry point so the executable program exists in the bin folder so the following invocation works fine: cppcheck-codequality --input-file=cppcheck_out.xml --output-file=cppcheck.json

Maybe I'm missing something here? If not, I suggest updating the README. I can send a patch if desired.
