Cleanup, async/await & let/const

[gdelmas]

hi @Quramy,

i made some further changes. mainly to async/await. but also some cleanup and the use of let/const.

for review it is probably worth looking at the changes at each commit one by one, as they are not a lot. the whole diff looks overwhelming and is not reflecting the steps well.

ahhh, i just noticed utils.promisify is not available in node 6. so test is failing. i will do a custom promisification.

would you generally be open to the changes? i think it is nice as it reduces the lines of code, by keeping the functionality.

hey @Quramy,

what do you think about async/await?

[Quramy]

@gdelmas Sorry for my late reply 🙇

I like async/await syntax too.

And for now unit testing is run in Node.js v6 env, but I think almost dev uses Node >= v8. So we no longer need to support v6.

You can remove https://github.com/Quramy/typed-css-modules/blob/master/.travis.yml#L9 and use promisify.

hey @Quramy,

great to hear from you and happy you also like async/await better. you are completely right, without node6 support there is less code to maintain. i added a new commit to remove node6 support, where i also added the required node version to package.json so that some developer installing this might get a warning. i kept the commit with node6 support in the history, in case someone needs it and wants to fork.

Thanks for your great work!!!
