-- | Use this method to send audio files,
--   if you want Telegram clients to display
--   the file as a playable voice message. For
--   this to work, your audio must be in an .OGG
--   file encoded with OPUS (other formats may be
--   sent as Audio or Document).
--   On success, the sent Message is returned.
--   Bots can currently send voice messages of up
--   to 50 MB in size, this limit may be changed in the future.
