Highlight string interpolation

Ref https://github.com/JuliaLang/julia/issues/9025

ruby-mode does this, it would be nice to do it in julia-mode too. E.g. println("hello $user") should highlight $user differently.

This seems to require parsing arbitrary expressions. I would say not worth it just for this.

I'm really for at least a simple variant of this. As long $ is not "escaping", it can be really confusing:

This actually prints the literal string , expr.head, ( (what I intended was of course $(...something...)().

I think VS Code uses tree sitter. That's what we aim to do here too (cf #174 for progress).

[kurt-steiner]

so how is the progress ?
