Temporary fix for #1191

Reduced the core temporary changes to 1 commit. In separate commit changed version to v6.0.0-beta.0.

Runs as expected on Mac OS 13 with Apple Silicon (Arm64) mac.

Though I saw some serious issues with periodic packet loss (probably not real, but I don't know) using Ganglion v3.0.1, BrainFlow 5.10.0, and Native Bluetooth. @philippitts

Update: I also re-uploaded 3.0.1 firmware just to make sure. For some reason, when I check the version using nRF connect app still shows 3.0.0.

There was an issue with the Ganglion v3.0.1 build posted on the releases page as discussed here. Can you try re-downloading and flashing the Ganglion v3.0.1 firmware?
