Adding the new code-gen package

[SergioCasCeb]

This PR is meant to include the code generator as a new tool within the td-tools repository.

Although it can already be used, this package still lacks the appropriate bundling (browser and esm). I attempted to generate the respective bundles with browserify and babel as well as with esbuild, but they all failed, and I have not been able to make them work properly.

• Browserify and Babel failed even to create the bundle, so it cannot even be tested.
• Esbuild creates the respective bundles, but when trying to implement them in Playground, it fails.

This link shows the esbuild.js file that I was utilizing for the esbuild bundling. @relu91 Since I am using basically the same esbuild file that was used for the node-wot browser bundle, do you by any chance know what might be happening, or any recommendation in general?

Also, for more context on what is going on, here are a few screenshots of the errors that I always end up encountering.

Notes:

• Tests will be added later on.
• The way to get the Templates will also be changed to not rely on fetching from GitHub.
• The contribution section within the README file will also change once the Templates are fixed.

To clarify, are you trying to bundle the whole tool or just the generated code? if you are trying to bundle the whole tool, what is the purpose? support both browser and node?

The purpose is to bundle the whole tool to better support browsers and Node.
