Clear and concise description of the problem

Would it be possible to add an entryFileNames option to override the bundler configuration?
I'd like to generate .d.ts files with a different format than .js files.

I can't currently build a library with vite by specifying the output fileName because I have to set the entryFileNames option in rollup output.

Suggested solution

Pass entryFileNames as plugin option:

isolatedDeclPlugin({ entryFileNames: '[name].[ext]' })
