Delete ez_setup.py

It's obsolete.

Good call! Also need to update setup.py I think:

snakeviz/setup.py

Lines 3 to 8 in 1da62e1

	try:
	from setuptools import setup
	except ImportError:
	from ez_setup import use_setuptools
	use_setuptools()
	from setuptools import setup

Oops, right you are. I was also thinking it would be good to replace the setup.py with a setup.cfg + pyproject.toml, but I was going to do that separately.
