refactor: make lodash a devDependency

[jrop]

I attempted to run tests on my Mac, but was unable, so I am starting this PR in hopes of starting the discussion of removing lodash as a hard dependency from this library. lodash has been left as a devDependency, however.

Please let me know what you guys think!

The repo of this project is unmaintained more than a year, and we had build new version https://www.npmjs.com/package/@react-google-maps/api

We had rewrite it to TypeScript, and updating it frequently: https://github.com/JustFly1984/react-google-maps-api/tree/master/packages/react-google-maps-api
You can enjoy autocomplete.

You can see our docs: https://react-google-maps-api-docs.netlify.com/

Also a lot of examples: https://react-google-maps-api-gatsby-demo.netlify.com/ https://github.com/JustFly1984/react-google-maps-api/tree/master/packages/react-google-maps-api-gatsby-example/src/examples

The bundle size is much smaller: https://bundlephobia.com/result?p=@react-google-maps/api@1.7.5

Enjoy!
