[FEATURE] Format conversion

[defaultsecurity]

Would it be possible to add an automatic, optional format conversion, perhaps using ffmpeg internally? For the OpenAI-compatible HTTP server?
Thus parakeet.cpp could accept other formats as audio/webm, audio/ogg, audio/wav, audio/mpeg, audio/mp4, audio/m4a, audio/aac, audio/flac, video/webm, video/mp4.
This would be extremely helpful since other services rarely use wav/pcm as output. Non-steaming only.

A server-side conversion layer would broaden compatibility, but embedding ffmpeg also changes binary size, licensing/package dependencies, and attack surface. The maintainable boundary is likely an optional external ffmpeg invocation or documented proxy/transcoding layer rather than linking it into the core engine. @mudler this needs a scope decision before implementation.
