Updated schema of elk configs to be valid

• ELK no longer supports mode. Updated to use two channels instead.

@razerbeans just to state the obvious so I'm sure I understand, this fix to NeuralPi works on the latest 1.0 elk release?

[razerbeans]

@GuitarML Correct, this'll be for v1.0.0

This seems to have stopped working. I have a elkos v1.0.0 installed on a raspberry pi 4 and I am getting track fails:

I have tried the config files that come with the release as well as manually downloading from elk_configs.
