Fix for Python 3.7

[hb-alexbotello]

Fixes #233

According to PEP 479, if raise StopIteration occurs directly in a generator, simply replace it with return.

This is both backwards and forwards compatible code.

Returning from a generator is the correct way to generate StopIteration here. Tests continue to pass.

@adrian-the-git, @josegonzalez @hb-alexbotello Thanks for fixing this. What is the state of this PR? I’d love to see the changes released, so that fuzzywuzzy works smoothly again with Python 3.7.

I no longer work at SeatGeek and therefore have no commit rights (hurray offboarding!). Hopefully there is someone on the SG dev team that is reviewing PRs for OSS repositories, but it's not going to be me.

[hb-alexbotello]

Unfortunately, it seems no one has yet taken up the mantle in your place.

[adrian-the-git]

Is it time to fork this project?

[paulgoetze]

Hey @garetht, I saw you making some changes in SeatGeek’s Python repos recently. Maybe someone at SeatGeek could have a look again? Else I’d also be happy to get involved and help as a maintainer of fuzzywuzzy in the long run.

@hb-alexbotello thanks for the contribution! I'll try and contact the relevant people to get this published.

[haykkh]

Any updates on this @garetht? fuzzywuzzy seems to be entirely useless in a lot of use cases until this is fixed.

[garetht]

Ah sorry I'm going to try and ask for credentials again to publish this myself.
