Support for outputting bundles with JSX extensions

[XiNiHa]

While Nanobundle respects "jsx": "preserve" in TSConfig and emits it as-is, I found that it doesn't accept JSX family extensions (.jsx, .mjsx, .cjsx) as output file extensions (instead it tries to look for something like index.mjsx.js, ...)
Outputting files with JSX extensions is important because Vite doesn't accept JSX when the extension is just plain .js. Transpiling the JSX when bundling isn't an option that I can consider. (since I'm currently building a library that exports a component for SolidJS)
Would it be possible to support outputting files with JSX extensions?

This will be allowed in v1.1.0, but generally not recommended
