This crate will no longer be relevant after we export esm information
directly from the parser.
Besides, `ex-module-lexer`'s output data is too limited for plugin
authors to use.
- Added TypeScript annotation for `ParseResult.program`
- Modified the entrypoint for `oxc-parser` to allow wrapping the napi functions
- Updated `index.js` to parse the `program` string into a JSON object
- Updated tests
- Added a dependency on `@oxc/types`
