Do you have an example about how to generate ES5 for IIFE and ES2025 for ESM ?

Do you have an example how to change the language output depending on the output format when compiling multiple bundles?

i.e.
```		
compiler({
   language_in: 'ECMASCRIPT_2017',
   language_out: 'ECMASCRIPT_2015'
}),
```
