Reduce battery consumption and minimum requirements of CrystalSound

I wouldnt wanna compromise on quality for the sake of battery. I say this since I use it on a fixed classroom setup. I am sure business users who are always on the move will appreciate it.

What I’d like is to offload the processing to a SBC like RPi (or something more apt for CrystalSound, like a GPU/NPU for the AI, etc) which is fairly cheap and globally available.

i made a request of the same in #21
