* Converts a list of globs into a function that matches a path against the
* globs.
*
* Every time micromatch is called, it will parse the glob strings and turn
* them into regexp instances. Instead of calling micromatch repeatedly with
* the same globs, we can use this function which will build the micromatch
* matchers ahead of time and then have an optimized path for determining
* whether an individual path matches.
*
* This function is intended to match the behavior of `micromatch()`.
*
* @example
* const isMatch = globsToMatcher(['*.js', '!*.test.js']);
* isMatch('pizza.js'); // true
* isMatch('pizza.test.js'); // false
