humanize raises DeprecationWarning upon import

[jwodder]

As of humanize 3.13.0, simply doing import humanize causes a DeprecationWarning to be emitted about Unit. This is a problem for libraries that use humanize and whose tests are run with filterwarnings = error or equivalent in effect.

What did you do?

python3 -W error -c 'import humanize'

What did you expect to happen?

A lack of an error.

Ah, sorry about that, it's unintended from #234.

@samueljsb Please could you check it?

I don't have access to "yank" the release, but I can comment out this particular warning and put out a quick point release.
