firebase library is wrongly bundled in react-firebase-hooks/auth #121
Description
The transpiled react-firebase-hooks/auth code includes firebase library code, but I believe it should be omitted.
Note the sizes of the following files are grater than 200KB, but the sizes of the others (e.g. react-firebase-hooks-firestore.js) are less than 5KB.
