Changed: - Move most library components to new [`vorago-shared-periphs`](https://egit.irs.uni-stuttgart.de/rust/vorago-shared-periphs) which is mostly re-exported in this crate. - Overhaul and simplification of several HAL APIs. The system configuration and IRQ router peripheral instance generally does not need to be passed to HAL API anymore. - All HAL drivers are now type erased. The constructors will still expect and consume the PAC singleton component for resource management purposes, but are not cached anymore. - Refactoring of GPIO library to be more inline with embassy GPIO API. Added: - I2C clock timeout feature support.
