Please support node 4

Hey, I just cloned consolemock and ran the check on node v4.0.0 and it was successful. Do you mind adding support for node 4? We want to use this module in lint-staged for snapshot testing with jest. But we support node 4.2 and above and hence the request. If it is as simple as changing the engines.node field in the package.json and circle.yml, I could make a PR if you’d prefer it.

Thanks @ttmarek!

Array.prototype.fill is not a problem:

λ node
> process.versions.node
'4.0.0'
> [1, 2, 3].fill(1)
[ 1, 1, 1 ]

Could you run a check to make sure nested groups work

yarn run check was successful. Is there anything else I would need to test?

And YES! I would love to accept a PR. 💯 🥇

I’ll make a PR for this tomorrow 😄
