Allow the library to be consumed from client side

[nitzano]

Describe the solution you'd like

We want the o use enum-converter from client-side, for that there
there should be added a solution for consuming from web (currently buggy).
Solution can be either be by code or adding appropriate documentation.

Is your feature request related to a problem? Please describe.

Yes, enum converter cannot be consumed/compiled from web applications.

Working on this at #goodnessSquad event

I believe it may be possible to run browserify on a file that imports and exports convertString.
In order to simulate fs we can use browserify-fs and run something like:

browserify ./src/browser.s -r browserify-fs:fs -o ./lib/enum-converter.browser.js

But the problem is that is simulates only the async API. So we should change writeFileSync to be writeFile, preferably also using promisify with async/await.

Also this will also probably require babelify and maybe other browserify plugins.

I will give this a shot.
