* commit debug code to save it due to merge * migrate first devices to new device registry and configure on runtime * fadecandy and rs232 resets device if config is set * try to hunt crash on osx * test commit if this works with osx * refactor spi devices * cleanup * refactor leddevices file, tinkerforge and ws2812b * refactor raw usb devices * refactor udp devices * - add tpm2net driver - remove old udp driver from build (files left in place for reference for new udp driver) - json serverinfo shows available leddevices * finish rework part 2 of leddevices * add schemas for leddevices. currently only compiled in, but not usedx
