Add Typescript definitions

[BearToCode]

I added custom d.ts types definitions for the main entrypoints, closing #32.
I also changed the build process as following:

• Add dist folder to .gitignore.
• Add Rollup with a bunch of plugins to:
  • Minify the build,
  • Fix dynamic imports([BUG] Unable to import language when bundled by Vite. #31),
  • Copy types definitions into dist directory.
• Add custom cjs build inside dist/node directory.
• Add files: ["dist"] in package.json to only include build files in published package,

Thanks for your pull request! Looks great! 👍

It looks like adding the dist folder to the gitignore has caused problems with the Deno package functionality. To resolve this, we may need to consider reversing that particular change.

Additionally, after merging the PR, the bundle size has increased significantly due to the dynamicImportVars plugin and the large switch case it creates. To make sure this doesn't negatively impact users who are not using Vite, we should work on separating the Vite version of the build from the main build.

Regarding dynamicImportVars: if you prefer a smaller bundle size you can remove that plugin, but maybe add a mention of the issue in the readme so users can get a workaround.
Could you be more specific about the Deno problem? I might also look into that.

I also noticed a few options that need to be changed regarding types that I forgot to put in my previous PR, so you may want to wait so that I can add them in a new PR.

@matubu I created a new PR for the fixes I mentioned (#35).

I think the problem with Deno is that the .zip file bundled in the GitHub release does not contain the dist folder. I did not understand how the release is created in the action, but I think that you to have to make the runner execute npm run build, zip the dist folder and use that in the release. (At least, that's my guess but you better check yourself)

Thanks for your PR, @BearToCode. I will work on fixing the deno package issue
