Add a babel preset with this enabled

I did the work but great if someone took it off my hands

Hi @fivethreeo thank you! I'm sure this would be cool, but doesn't match the repository scope. I'll leave this open in case someone else find it useful / would like to publish it

By the way I use this plugin without the preset here: https://github.com/jaredpalmer/razzle/tree/master/examples/with-typeorm-graphql 😀
