Assist mic feature - snd response elsewhere

[AlfredJKwack]

Objective:
Provide a means for the Wyoming Satellite audio to be piped elsewhere.

Technical choices:

• Use --synthesize-command offered by the upstream Wyoming Sattelite repo.
• Use HA's webhook API for flexibility (and to avoid generating long lived access tokens)

Considersations, limitations and things

• TTS is still getting processed. See upstream wyoming-satellite PR #227 for how that may be adressed down the line.
• This won't send the --awake-wav and --done-wav to wherever you send the text to be synthesized to.

Reference conversations:

• Send response from satellite somewhere else
• Output returned audio to SONOS speaker from usb microphone
• Reusing Google nest speakers for response, but with Assist microphones, TTS
