Use python-dateutil package instead of dateutils

[meatcar]

While working on updating sqlite-utils for NixOS/Nixpkgs, I came a cross the following:

In 5ec6686, a new dependency was added on dateutils (https://pypi.org/project/dateutils/).

I believe this is unintentional, and instead python-dateutil (https://pypi.org/project/python-dateutil/) was intended.

My reasoning is:

• python-dateutil is imported here in recipes.py
• The mypy type-python-dateutil dependency in setup.py
• python-dateutil is a dependency of dateutils as seen in the output in docs/tutorial.ipynb

Seems like the trailing "s" seems to be the source of confusion 😅

I've swapped the dependencies out, hope this helps.

Yes this was absolutely the intention! Thanks, I wonder how often I've made that mistake in other projects?
