Allow require imports

[mateotomas2]

Description

Package.json exports is not defining a file to use when you use require only for import.
This is why I changed import to default so it handles both as a fallback. Maybe this is not correct and it should match a different file but this works for me.

Context:

I have a monorepo repository with a shared project imported in a react+vite project. And when I run the client in development mode I get this error:

'Failed to resolve entry for package "sirdez". The package may have incorrect main/module/exports specified in its package.json: No known conditions for "." entry in "sirdez" package'

Maybe it's a problem in my tsconfig or vite configuration, but this PR fixes it.

Oh I almost forgot to thank you for this cool library :D
