refactor(groupBy): Remove Map polyfill
- Removes Map polyfill - Removes FastMap impl - Tests in latest Chrome and Node show no discernable difference in performance between Map<string, T> and Object has a hashtable for our use case. - Adds an error that is thrown immediately at runtime if Map does not exist. BREAKING CHANGE: Older runtimes will require Map to be polyfilled to use `groupBy`
