And another tumblelog update

In the afternoon I pushed a small tumblelog update to GitHub. The changelog for version 6.3.0 is as follows:

• Improve typing hints (tumblelog.py)
• Use int for years in create_year_pages and create_tag_pages (tumblelog.py)
• Check page names are unique and don't conflict with blog
• Format year correctly (tumblelog.py)
• Move setlocale to main (tumblelog.py)

I really like mypy to check type hints. Together with dataclasses, introduced in tumblelog version 6.2.0, it makes the code much cleaner.
