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'
}),
```

Start by reviewing the existing documentation and compiler configuration examples for multiple bundles. Use the issue's IIFE/ESM and ECMAScript version requirements to frame an example, and consider the work done when it shows how each output format receives its intended language target.
