Porting to XMOS XU316

[alextrical]

Hi All

It would be useful to have this ported to XMOS XU316 as this chip is being use by numerous community projects, and is capable of running Tensorflow Lite models.

So far the following projects are making use of this chip, with more likely to follow:
Nabu Casa: VPE (Voice Preview Edition)
FutureProofHome: Satellite1
Seed Studio: ReSpeaker Lite

The XU316 is paired with a ESP32-S3, We are currently running mWW on the ESP32-S3, but due to limited resources available on the ESP32-S3 would greatly benefit from running the mWW model on the more powerful cores of the XMOS chip

The currently supported WakeWords are Cyberon and Sensory (VoiceHub) but these are licenced solutions, and not really suitable for the community project use, so I’m hoping we could help work towards using this project.

Kind regards
Alextrical
