Enables hashing of all classes (default: false).

If a function is given it can be used to hash only certain classes:

{
  hash(className, defaultHash) {
    if (/^[~@]\(/.test(className)) {
      // a shortcut like `~(...)` or apply like `@(...)`
      return defaultHash(className)
    }
    return className
  }
}
