Description

Currently the pins always implement both InputPin and OutputPin even thought the pin might not be in the correct mode, and presumably trying to use it in the wrong mode either doesn't work or causes an error.

This could be done neatly with type states and into_output style methods like many other HALs. This would also make them more convenient to use as the user then doesn't have to manually set the correct mode before constructing the pin.

Research direction

Start by locating the GPIO pin implementation and reviewing how pins currently implement the InputPin and OutputPin traits. Compare the existing API with type-state and into_output patterns in other HALs, then define and verify mode-specific pin types and conversions without requiring manual mode setup.
