Upgrade stack to ES Modules and TypeScript

[noherczeg]

Time has passed since the inception of this library and so did standards and best practices when it comes to JavaScript libraries.

Given that we already had a request at #43 I took the initiative to update the stack with the following concepts:

• Added support for NVM to make NodeJS version maintenance easier
• Added Biome formatter to keep the code format consistent
• TypeScript makes source code less error-prone due to it's type-system, and checks
• The ECMAScript standard has evolved, now ES Modules are standard, there is no need for require
• Build pipeline was outdated, moved to Vite
• Tests have been migrated to Vitest to keep the stack concise

This PR is not yet finished, most of the docs need to be updated, but every test runs, and examples are working.

Looking forward for your response.

As a side-note: I didn't want to re-write the whole code-base from scratch, therefore larger files are kept as-is, and inheritance hasn't been applied everywhere (yet?) although I think we could.

@noherczeg Thanks for this work, but not sure what to do about it. I definitely will not support this project anymore as you see how old are those last commits.
I can merge it but not sure I can or remember how to publish it.
Would it make sense for you to just fork it if you really want to use it?

Thank you so much for your amazing work on this project, it’s been incredibly valuable to us. We wanted to let you know that we plan to move our modified version of the library under our organization, BlackBeltTechnology, with a new name, ecore-ts, and publish it on NPM.

We’ll make sure to credit your original work both in the documentation and metadata so your efforts are properly recognized. If you have any concerns or feedback, please let us know!

Thanks again for creating such a great foundation.

Best regards,
Norbert
