Helium Firmware version updated to 2022.05.19.0_GA

From Helium:

This release is highly recommended for all Hotspot Makers.

This update adds a retry delay when sending PoC Witness Receipts (from a Hotspot to a Validator) so that it has a better chance of succeeding if the Validator falls behind a few blocks from the tip of the chain.

Hotspots without this release will still function but will greatly improve rewards. No action is required by Hotspot Owners.
