Split the library into server side and client side

[francisconeves97]

This library contains server side and client side helpers. To allow for different use cases and creating different client side wrappers we should split this library into two: google-forms-parser for the server side and react-google-forms-hooks for the client side. react-google-forms-stack could also be created containing both utilities for people with simpler use cases.

@francisconeves97 I think you can safely close this issue, the original tasks are all solved now.
