Notification: Support for Python 2 is ending

In the near future, Lark will drop support for Python 2. We will continue to develop for Python 3.6+ only, which will simplify the code and ease development.

Old releases (including this one) will still work, of course, and should be stable enough to accompany the remaining Python 2 users into the sunset.

If you have any objections, feel free to voice them here: #874

Thanks for everyone who helped make Lark better!
