Hotspot Firmware Release: Improve ECC Slot Handling and re-enable Gateway-rs Packet Forwarding

The Helium team has tagged a new 2022.03.29.1 firmware release for Original Helium and RAK/MNTD Hotspots.

This release fixes a regression in ECC key slot handling. Earlier firmware releases specified ECC key slots 0 and 15 for public and onboarding keys, respectively. However, recent releases specified slot 0 for both. This release reverts sys.config to the old spec. Note that slot 15 was only used for some very early first generation Hotspots thus very few not-yet-onboarded Hotspots were affected by the reversion. No action is required by Hotspot owners.

Additionally, this release uses the embedded rust gateway and gwmp-mux processes to forward packets instead of the erlang miner, as a step toward the transition to Light Hotspots.

For those Hotspot owners flashing new SD Cards for RAK/MNTD and original Helium Hotspots, please use this base image going forward. No action is required otherwise, and all RAK/MNTD and original Hotspots will receive this update automatically over the air as long as your Hotspot is plugged in and connected to the internet.
