Remove test data files from published releases

[dosisod]

I was poking around my .venv folder and noticed that this library includes a lot of test data in the published package, which is weird because these files aren't in the test folder:

$ cd .venv/lib/python3.10/site-packages/multipart

$ find tests/ -not -ipath "*__pycache__*"
tests/
tests/test_multipart.py

How are these files getting into the releases? Do these files need to be there? Thanks.
