Tags and categories for posts

Added tags and categories for posts. I planned for long adding a feature like this, but avoided implementing it because I didn't understand what I did in filters.py. It's a beta feature and I probably will keep only categories or tags, but not both.

• Updated some documentation in top level README.md
• Added tags / categories to posts #100 😅
• Temporarily deactivated the mypy pre-commit hook because mypy 1.5.0 is not compatible with django-stubs
