Turned off XON and XOFF by default (turning them on now requires setting xon-xoff-enabled to non-zero) and made a fix to the chronic build issues by changing how make_image.sh and make_uf2_image.sh decide to finish downloading ihex-formatted images from the MCU.

This bug-fix patch-level release fixes an issue where the entirety of the full build on the RP2040 was not getting built properly, so words such as edit and restore-state were not getting incorporated into the full build binary and UF2 file. Only the full build for the RP2040 has been rebuilt, and the reported version numbers in the kernel remain at 0.36.4.

This patch-level release fixes a bug in upload mode in the line editor, which in particular would cause it to lock up on the Raspberry Pi Pico.

This patch-level release exposes more settings in the user-level pio module and also exposes speed settings in the pin module.

This patch level release fixes a number of issues with the pio module that rendered it not fully usable (e.g. sideset was broken).

This patch-level release fixes an important set of bugs in the PIO assembler which caused the number of bits specified for in,, out,, in+,, and out+, to not be assembled properly. Also, better documentation for the PIO assembler is included.

This release revamps the API of the pio module for the RP2040 (i.e. Raspberry Pi Pico) to make it more user-friendly and to provide more validation of values passed to it.

This patch-level release fixes a major bug in queue channels that was preventing them from blocking properly under certain use conditions.

This release revamps the pool module's API and fixes an important allocation bug in it. It also adds optimizations to the pin module on STM32 platforms.

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).
