build: prep for 2.5.0 - fix py versions, add links to pypi Mark supported python version as 3.7 or newer alphabetize args to setup so I can find them add project_urls for docs, changelog, contact, IRC issues licenses and wiki.

try:
    # Python 3+
    from time import perf_counter
except (ImportError, AttributeError):
    # Python 2.5-2.7
    from time import clock as perf_counter  # noqa: F401
