Disentangle LedDevice/LinearColorSmoothing, Bug Fixes & Test support (#654)
* Handle Exceptions in main & Pythoninit

* Have SSDPDiscover generic again

* Have SSDPDiscover generic again

* Change Info- to Debug logs as technical service messages

* Nanoleaf - When switched on, ensure UDP mode

* Include SQL Database in Cross-Compile instructions

* Fix Clazy (QT code checker) and clang Warnings

* Stop LedDevice:write for disabled device

* Nanoleaf: Fix uint printfs

* NanoLeaf: Fix indents to tabs

* NanoLeaf - Add debug verbosity switches

* Device switchability support, FileDevice with timestamp support

* Nanoleaf Light Panels now support External Control V2

* Enhance LedDeviceFile by Timestamp + fix readyness

* Stop color stream, if LedDevice disabled

* Nanoleaf - remove switchability

* Fix MultiColorAdjustment, if led-range is greater lednum

* Fix logging

* LedFileDevice/LedDevice - add testing support

* New "Led Test" effect

* LedDeviceFile - Add chrono include + Allow Led rewrites for testing

* Stabilize Effects for LedDevices where latchtime = 0

* Update LedDeviceFile, allow latchtime = 0

* Distangle LinearColorSmoothing and LEDDevice, Fix Effect configuration updates

* Updates LedDeviceFile - Initialize via Open

* Updates LedDeviceNanoleaf - Initialize via Open, Remove throwing exceptions

* Updates ProviderUDP - Remove throwing exceptions

* Framebuffer - Use precise timer

* TestSpi - Align to LedDevice updates

* Pretty Print CrossCompileHowTo as markdown-file

* Ensure that output is only written when LedDevice is ready

* Align APA102 Device to new device staging

* Logger - Remove clang warnings on extra semicolon

* Devices SPI - Align to Device stages and methods

* Fix cppcheck and clang findings

* Add Code-Template for new Devices

* Align devices to stages and methods, clean-up some code

* Allow to reopen LedDevice without restart

* Revert change "Remove Connect (PriorityMuxer::visiblePriorityChanged -> Hyperion::update) due to double writes"

* Remove visiblePriorityChanged from LedDevice to decouple LedDevice from hyperion logic

* Expose LedDevice getLedCount and align signedness
