Default to terser instead of uglifyjs

I've just read that uglify-js is actually no longer maintained. However, terser is, and it's recommended by elm-optimize-level-2 as a replacement. Maybe mkElmDerivation should use terser, then? Usage seems exactly the same as uglifyjs.

The reason I used uglify-js was because that is was that is what Evan uses in the minification guide.

I have actually updated the way mkElmDerivation works by default to make it less opinionated. Essentially, all this does now is fetch the elm dependencies and puts them in the right place. It's then up to the user to run whatever elm commands they want to.

I am happy to update to terser if you think that is a good idea, but it will be updating legacy functionality of this repository. Would you benefit from that?

Ahhh, I get what you're saying. It seems I'm still using an old version of mkElmDerivation that is more opinionated.

I will update mkElmDerivation then and get back to you.
