Add findNumbers functionality from libphonenumber

[catamphetamine]

As far as I can see findNumbers is not part of the original javascript package which is understandable because crawlers and parsers are backend-driven and are therefore written in CPP and Java.
https://github.com/googlei18n/libphonenumber/search?utf8=%E2%9C%93&q=findNumbers&type=
Though I used to code Java a lot in the past, I don't write any crawlers so I don't need that findNumbers function, but if you do you can write it though I'm not sure right now if it's needed in this library.
Given that ES6 brings tree shaking it might not have any impact on other users, but I guess rather than depending on me to publish your code you would prefer instead publishing your code in your own package so that you could be in control if you know what I mean.

Makes a lot of sense @halt-hammerzeit.
Are the any internal functions/regexes that this library could expose for me to build a package based on this one?

If you happen to need any (in the final code) then leave a comment here and I'll export them.
Until you're ready to publish you can copy&paste them (i modified some of them a bit, btw).
Since you'll be migrating a Java version, I'd suppose you'd better stick with the original regexps since they're untouched.
