Cannot be used in webpack/browser, due to require("fs") #157

Most of this library works perfectly fine between NodeJS and the browser/Webpack.

However, there is one line that breaks it for the latter: https://github.com/soumak77/firebase-mock/blob/master/src/storage-file.js#L8

Ideally, there would be a way to exclude the NodeJS-requiring portion of the library, so you can use it from browser code.

This would be helpful because it means I can more easily integrate the mocking library with Cypress. (Cypress tests run in the browser alongside the main application code)

For now I'm getting around the issue by adding fs to Webpack's externals config:

webpackConfig.externals = {
    // needed for firebase-mock in browser (code-path not actually used, so it's okay)
    fs: 'root location', // redirect to some global-variable, eg. window.location
};
