Previously the code had canbus_read() which was called from task
context (for admin messages), and canbus_process_data() which was
called from irq context (used for data messages). Change that to a
single canbus_process_data() function that is called from irq context
(used for all messages). This simplifies the low-level hardware
specific canbus code and should make it easier to support other
hardware implementations.

Create a single CanData global variable to track the canbus state.
ARM micro-controllers generally produce better code when global
variables are in a struct.

Use a USB hex id to indicate that the device is already in bootloader
mode. This makes the rp2040 flashing code similar to the other
boards.

The CanBoot bootloader can often fit in 4KiB and that may be useful
for some devices with small flash sizes.

Just log an error on a fault.
Remove the host check for min/max temperature as the micro-controller
code already implements that check.

Allows a limited number of DS18B20 read failures
before stopping the printer. This is designed to
tolerate spurious read errors, while still stopping
for serious issues.
The printer will stop when the sensor
fails to report a value five times in a row.
Implementation works as follows:
The MCU reports any read errors using a new "fault"
parameter in its answers.
The Python code tracks the number of errors
and triggers the shutdown. This paves the way for
more sophisticated error handling in the future,
as well as an example for other sensors to follow.

When CanBoot is detected set its bypass signature when a
reset is requested.
Add a "try_request_canboot()" method that may be called
from from USB and Canbus bootloader requests.

Adding Klipper functionality to support cancelling objects while
printing.
This module keeps track of motion in and out of objects and adjusts
movements as needed. It also tracks object status and provides that to
clients.
The Klipper module is relatively simple, and only provides one piece of
the workflow. Moonraker already supports processing uploaded files to
insert the required gcode markers for cancelling objects, using
https://github.com/kageurufu/cancelobject-preprocessor. This library is
also available as an executable for use in slicers, and pip
installations also include the script as a callable.
Mainsail has integrated support, and code changes for Fluidd are
available. Support in other interfaces is planned, and we've spoken to
several other developers about integrating frontend support in their
projects.

in TEST_RESONANCES the CHIP parameter has been
renamed to CHIPS
