Output option of odfdo-styles script not working

[keestux]

The script odfdo-styles.py has a few problems. The -o is not working, there is a typo in a variable name, and with Python3 opening a file with wb requires bytes not str.

Anyway, here is a git-diff of the proposed changes (too lazy for a PullRequest right now):
