YAML based config for PI / Portduino (#2943)

* Add configuration via /etc/meshtastic/config.yaml

* Move example config, support more locations

* Fix config check

* Use access() to check for config file presence

* Throw an error and exit on radio init fail

* Adds error check for reading Bluetooth MAC

* Settle on meshtasticd, add install script

* Shell fixes

* Fine. I'll put it back and then disable you

* Get wrekt, shellchekt

* Firat attempt at adding raspbian CI build

* Tickle the workflow

* Beatings will continue til morale improves

* Permissions are overrated
