Upgrading to Less 3.x

[brendon]

Hi @cowboyd, I'm a maintainer for Semantic-UI-Rails-LESS and I've been attempting to update that to the latest version of Semantic-UI. Unfortunately they now require Less.js > 3.5 for some calculations to work correctly: https://github.com/Semantic-Org/Semantic-UI/blob/master/RELEASE-NOTES.md#version-241---oct-13-2018

I had a quick look at what it would take to upgrade less.rb to the latest version of Less. It seems that there are some problems with commonjs and lack of support for a few techniques required by the latest version of Less. To be honest, I'm finding the whole thing a bit hard to get my head around.

I was wondering if you had any appetite for looking into this? Is there an alternative to commonjs that could be used (and is maintained?) I assume the main reason for lack of activity on these gems is because of the move to webpacker.

Any help or direction you could give would be fantastic. :)
