Drop Python 3.8

[simonw]

It's time. EOL was a month ago: https://devguide.python.org/versions/

Today's 3.38 release still supports 3.8 (tests pass and it's marked as supporting it in the setup.py metadata) but I won't be supporting 3.8 in future releases.

sqlite-utils/setup.py

Line 67 in 1290c50

python_requires=">=3.9",

I can remove this note from the docs too:

sqlite-utils/docs/python-api.rst

Lines 2714 to 2722 in 1290c50

	Python 3.8 added the ability to register `deterministic SQLite functions <https://sqlite.org/deterministic.html>`__, allowing you to indicate that a function will return the exact same result for any given inputs and hence allowing SQLite to apply some performance optimizations. You can mark a function as deterministic using ``deterministic=True``, like this:
	.. code-block:: python
	@db.register_function(deterministic=True)
	def reverse_string(s):
	return "".join(reversed(list(s)))
	If you run this on a version of Python prior to 3.8 your code will still work, but the ``deterministic=True`` parameter will be ignored.
