Fix #99

Some issues fixed

Fixed audio output on Matrix Voice. 44100 stereo plays a bit too slow due to an unknown bug.

New version with animation for Matrix Voice and M5 Atom Echo. Also, all the various states have different colors, configurable by MQTT for now but a webUI config is on the todo list.

• Added ESP32_POE_ISO and TAUDIO
• Added animation function, work in progress
• Added Speaking state for animation preparation (works for matrixvoice)

- Adding better logic for saving settings in webUI
- Add actual hardware capabilities in webUI
- Restructure AudioKit code

Thanks to the work of @hogthrob the majority of the audio playback should be fixed. When using 44100 some jitter might occur, but no hissing or cracking

Saving of the configuration was causing unexpected instability issues. Now, when a save is needed, the system reboots.

Removed local hotword setting from UI and code until local hotword is ready.
