Added docs, test infra and export functions

[rubentebogt]

Hi @chinmaypurav, verry cool package this iss!

Would really like to use this in my projects, therefor i made the following changes, i hope you like them:

• Added basic dockblock documentation
• Fixed one or two small bugs
• Added basic infrastructure for Unit testing using PHPunit, coverage is not nearly a 100% but at least this gives us a start.
• Also i added some basic functions using a trait to export the generated json

Possible improvements i think would be:

• Adding the repo to packagist so that everyone can install.
• Implementing 100% testing coverage
• Implementing PSR-7 so that you could generate from existing request objects in other packages.

This requirement is not further required as we are on php ^8.0

PHP 8 ext-json

Hey @rubentebogt . Thanks for the PR. I will be reviewing it shortly.

As for your suggestions; this package is already available on packagist.org. I have not yet created a stable release, because there are a few additional changes I am working on.
This package is a dependency package for Postman Laravel which is my core focus.
