(Unicode C) VoiceBase -- Upload a media file for transcription and analysis

This example demonstrates how to upload a media file for transcription and analysis. It duplicates the following curl command:

curl https://apis.voicebase.com/v2-beta/media \
  --form media=@msg_123_abc.wav \
  --header "Authorization: Bearer ${TOKEN}"
