This release adds a new pin module that greatly simplifies interacting with GPIO pins and makes them as uniform as possible across all the supported platforms (the main differences being that on the RP2040 pins are simply GPIO pin numbers but on the STM32F407, STM32L476, and STM32F746 pins are expressed as a combination of a pin number on a GPIO and a GPIO). Additionally, it revamps the led module to make it significantly more uniform across all platforms with LED's (for instance on green led! will turn on a green LED on the Raspberry Pi Pico, the STM32F407 DISCOVERY, and the STM32L476 DISCOVERY whereas previously led-on was used on the Raspberry Pi Pico while led-green-on was used on the STM32F407 and STM32L476 DISCOVERY).
