* Wio-e5 / STM32WL wip

* Stubbing some FS stuff out

* LittleFS compiles. Can't check with actual device.

* make cppcheck happy again

* Guard against accelerometer thread

* Missed a spot

* Upload via ST-LINK

* Derive MAC address from UID

* upload port

* Trunk it

* Guard it

* Maybe fix the cache error on startup.

* Latest RadioLib ref to fix SubGHZ

* revert nasty Sub-GHz Hack

* Boots and radio inits with RadioLib 6.0, LittleFS doesn't seem to work
