redPanther d679affeb4 Leddevice rework2 (#193)
* 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
