Completely filling the spi transmit fifo could lead to a situation
where the rx fifo overflows. Make sure not to write past the rx fifo
size.
Also, be sure to wait for the transmission to fully complete before
exiting spi_transfer().

Avoid unnecessary (HAVE_STM32_CANBUS && MACH_STM32xx) checks in
Kconfig. The HAVE_STM32_CANBUS is a helper symbol for all the chips
that support canbus, there's no need to mix it with a check for a chip
that is already known to have canbus.

Validate host provided index prior to accessing memory using that
index.
Also, consistently use a uint8_t for max_sections (to account for
integer overflow issues).

Add a filter workbench Jupiter notebook to help printer developers tune filters based on probing data

Initial setup of Load Cell Probing. This implementation supports triggering from the Load Cell Probe on the MCU. It also supports, optiopnal, filtering of the force signal by sos filter to eliminate drift caused by bowden tubes or other mechanical causes.

As probes stop supporting `probe:z_virtual_endstop` this class will give users a polite and specific configuration error.

This is an implementation of the SOS fliltering algorithm that runs on the MCU.
The filter opperates on data in fixed point format to avoid use of the FPU as klipper does not support FPU usage.
This host object handles duties of initalizing and resetting the filter so client dont have to declare their own commands for these opperations. Clients can select how many integer bits they want to use for both the filter coefficients and the filters output value. An arbitrary number of filter sections can be configured. Filters can be designed on the fly with the SciPy library or loaded from another source.

There have been several optimization to the usb to canbus bridge code
since that statement and it is likely many setups can run a
SHAPER_CALIBRATE with all activity on a single 1mbit canbus.

Added a paragraph about flash loop protection on some motherboards. It has been noted that not all people know about the need to change the bin filename on some stock boards or other methods that may hinder progress.

The docs aren't particularly clear that if you generate a mesh in our start g-code, you can just use it without additional commands. This is causing issues with support on r/klippers

Add a new G-Code command that can register a manual_stepper as an
additional axis on standard G-Code G1 commands.

Add a new add_extra_axes() to support adding additional axes. Once
called, toolhead.get_position() will return a list object with more
than 4 items, and toolhead.move() requires the same size list.

It's not valid to alter the extruder position from a call to
set_position(), so don't allow callers to attempt that.

Make it more clear that stepper_load_next() has three separate code
paths - one for each of the optimized stepper_event_X() functions.
