Wio-e5 wip (#2265)
* Wio-e5 / STM32WL wip * Stubbing some FS stuff out * Wio-e5 / STM32WL wip * Stubbing some FS stuff out * Wio-e5 / STM32WL wip * Stubbing some FS stuff out * 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 --------- Co-authored-by: Thomas Göttgens <tgoettgens@gmail.com> Co-authored-by: GUVWAF <thijs@havinga.eu>
