Bumped Calibre to 1.16.0

I have an idea: Since I’m particularly interested that this package and the CDBurnerXP package are up-to-date, what if you would make me a co-maintainer of these? I update my [automatic packages](https://github.com/TomOne/chocolateyautomaticpackages) almost every day, and without wanting to brag, I think I’m currently a quite reliable package maintainer.

It’s just a suggestion. :smiley:
