Upgrade check-types to 1.1.x.

Hi, dev at Amazon here. I'm integrating complexity-report into my team's process, but ran into some issues with mixed dependency versions of check-types. Seems escomplex-js and escomplex use check-types 0.7.x, while complexity-report has an immediate dependency on check-types 1.1.x. To fix this on our end, I upgraded escomplex and escomplex-js to use check-types 1.1.x. Figured I'd send this change your way if you wanted to make use of it. Cheers.
