Display minified / gzipped size in Readme

[diingo]

JSS says it's small. kb numbers would be great to know

I won't maintain kb numbers in the documentation manually ..., you might want to send me a PR which calculates it on build and replaces in readme :)

As a developer evaluating JSS, it certainly looks interesting, but I want to know how much it's going to cost in terms of file size. Even if not 100% accurate, a rough kb estimate makes these decisions much easier for new adopters.

you see the minified file in the dist ...

[gilbert]

Yes, and of course I could also download it and run gzip in the command line myself if I wanted to put in that much effort. What I'm suggesting is to add a couple numbers to the readme for the benefit of the project. The idea is you directly show people important, relevant information, as opposed to making them dig around for it. It's a small, but effective marketing tactic.

ok lets add appr number in kb ...
