## Changes
- GPIO HAL: `Direction`, `GpioOperation` and `Levels` are enum classes now, which prevents
name clashes with Windows defines.
PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/572
- New CMake option `FSFW_HAL_LINUX_ADD_LIBGPIOD` to specifically exclude `gpiod` code.
PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/572
- HAL Devicehandlers: Periodic printout is run-time configurable now
- `oneShotAction` flag in the `TestTask` class is not static anymore
