/**
* This splits a string on a top-level character.
*
* Regex doesn't support recursion (at least not the JS-flavored version).
* So we have to use a tiny state machine to keep track of paren placement.
*
* Expected behavior using commas:
* var(--a, 0 0 1px rgb(0, 0, 0)), 0 0 1px rgb(0, 0, 0)
* ─┬─ ┬ ┬ ┬
* x x x ╰──────── Split because top-level
* ╰──────────────┴──┴───────────── Ignored b/c inside >= 1 levels of parens
*
* @param {string} input
* @param {string} separator
