Gem release latest

[headius]

The latest matrix gem is from late 2018 but there have been fixes and enhancements since. JRuby now sources this library from the gem, so we have spec failures based on latest ruby/spec.

We need to get a gem release with the latest sources.

Seems like those files are just not in the gem? 🤔

I finally synchronized the main repo with this one (there were missing commits in both directions). I got version 0.2.0 with the same code by rewriting history a little bit for this repo (although I haven't released a 0.2.0 as I doubt it would do anyone any good).
Since there were some meaningful recent changes, I released 0.3.0 which I hope will work for everyone 😸 (let me know if you encounter any issue).
Thank you for your patience.

@marcandre Thank you!
