prompt: We are currently solving the following issue within our repository. Here is the issue text:
  --- BEGIN ISSUE ---
  Add FileClassifier media support
  **Is your feature request related to a problem? Please describe.**
  As a user I want to add WhisperTranscriber in my pipeline. I would like to use FileClassifier to classify my documents/media and direct to the correct node. 
  
  **Describe the solution you'd like**
  - Add support to media files (that Whisper allows) into the FileClassifier
  
  **Describe alternatives you've considered**
  Keep as it's and don't integrate into the current pipelines
  
  **Additional context**
  This feature request is supposed to be considered after the merge of the current Whisper PR #4335.
