Rhasspy TTS Hermes MQTT Service

Implements hermes/tts functionality from Hermes protocol using any of the following command-line text to speech systems:

• eSpeak
  • espeak --stdout
• flite
  • flite -o /dev/stdout -t
• PicoTTS
  • pico2wave.sh (in bin)
• MaryTTS
  • marytts.sh 'http://localhost:59125/process' {lang} (in bin)

Use --play-command aplay to play speech locally instead of using hermes/audioServer<siteId>/playBytes.
