New Murata lora chip with integrated STM32

@Gordon that RAK8211 looks interesting. But expensive. Would you be able leverage your clout with RAK if as a forum we wanted to set up a group buy? Just thinking out loud.

Also, at risk of asking a dumb question. The lack of a bootloader means we need another expensive piece of kit to work with these and this seems to be common on any BT boards you don't directly produce. But when OTA firmware updates on Puck and Pixl are so easy why is a bootloader not standard feature for these other boards?
