Feature request: Cache support for utility functions

# Feature Request

Amazing lib, thank you for making it 🙏🏻 

Have you considered supporting caching for the [utility functions](https://github.com/wellyshen/use-places-autocomplete/blob/master/src/utils.ts)? I'm looking for ways to reduce my places API cost.

## Describe the Feature

Support the existing caching mechanism on utility functions in addition to the autocomplete API.
