Fix for #338 (comment)

@jaraco It might be out of scope for this PR, but what do you think about completely removing pkg_resources as a dependency? Looks like the only other place it's used https://github.com/pypa/twine/blob/master/twine/package.py.

I peeked at that briefly and decided it was out of scope, but I'm in favor of getting that out also, but separately.

@jaraco I fixed the typing errors for 3.6 and 3.7 in 0d5aab4.

Is there anything else to do with this before merge? Maybe a changelog entry? 😉
