fix: package.json

[jiby-aurum]

Adds type and exports field in package.json for better support with node and typescript compiler, as well as modern dev tooling.

For my specific use case, without this vite-node does not handle this module properly. It ends up creating multiple instances of the module rather than a shared one.

@Abraham first of all thanks for your work on the library, was really helpful for me to achieve a use case I had with a vite based dev environment.

I just noticed as the last blocker letting me use it properly, would appreciate if you can release this soon :)
