npm Package Integration for Deno Application

This pull request addresses issue #58 and implements the necessary changes to make Deno application available as a functional npm library.

Key Changes

1. Bundling Solution:

   • Implemented a robust bundling strategy to resolve import issues, particularly with the jsonld library.
   • Utilized an import map file to manage dependencies more effectively.

2. Custom Document Loader:

   • Developed a customDocumentLoader for the jsonld.expand function.
   • This loader fetches the schema.org schema from a dedicated JSON representation, circumventing the need to pull from the main schema.org link directly.

3. npm Library Structure:

   • Added essential files and configurations required for npm package functionality.

4. Default schema file

   • Added a local schema file to import in cases where schema pull fails.

5. Ensure exit

   • Added an explicit exit() command at the end of the main function to handle cases where process hangs within npm.

Technical Details

• The bundling solution addresses limitations encountered during the web app setup, where the jsonld import was isolated to the file I/O components.
• The custom document loader enhances reliability and performance by utilizing a more stable JSON source for schema.org data.

Additional Files

This PR includes several new files necessary for npm package integration:

• .npmignore (for excluding unnecessary files from npm library)
• package.json (for defining npm library metadata)
• build.ts (for bundling)
• import_map.json (for handling npm:jsonld import outside of bundled code)

Testing

If possible, reviewers could try out installing and running the app through npm as a test:

nvm install 18
nvm use 18
sudo npm install -g psychds-validator
validate <path_to_input_dir>
