Calling python functions can have high overhead. Inline the
twos_complement code in the _extract_samples() inner loop.

The MPU9250CommandHelper() class is nearly a duplicate of
ADXL345CommandHelper(). Rename ADXL345QueryHelper() to
AccelCommandHelper and remove user facing references to "adxl345". Use
it directly from mpu9250.py .

The mpu9250.ClockSyncRegression() class is a duplicate of
adxl345.ClockSyncRegression(). Remove the duplicate copy and use the
code from adxl345.py .

Adds a save_config_pending_items to the status reported by
configfile reflecting the items and values that a future
SAVE_CONFIG would actually persist.

Move the uuid hash calculation to canbus.c and call canbus_set_uuid()
from src/stm32/chipid.c . This simplifies the low-level canbus
hardware code.

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.

Introduce support for the stock Creality CR10 v3 printer, including the filament runout sensor. It also supports the optional BLTouch.

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.
