The required tap_threshold value changes with the distance traveled
during each sensor sample. So, probing at a higher speed would
require a higher tap_threshold and a lower sampling rate would also
require a higher tap_threshold. To avoid future issues with this
scaling, change the code to automatically scale the requested value by
speed and samples per second.
As a result of this automatic scaling, existing user configurations
will need to change. It is hoped that existing configurations will
have a value that is sufficiently low that they will reliably get an
error until they can recalibrate.

Print near the origin lead in to fast motor movements, therefore the
movement needs to be scaled down. The start of the scaling is done via
a rotation velocity limit from the config.

Adds two checks to prevent config settings which could lead to div-by-zero errors in specific circumstances:
- `raw_dia1` and `raw_dia2` must be different to prevent a possible exception in `adc2_callback`
- `max_difference` must be less than `default_nominal_filament_diameter` to prevent a possible exception in `extrude_factor_update_event`
Doc is also updated.

Adds a toggle to enable or disable flow compensation based on the
filament width sensor readings without disabling the sensor entirely.
Useful on printers where the hall effect sensor is too inaccurate to
helpfully adjust the extrusion multiplier, but is good enough to act as
a filament runout sensor.
The new setting defaults to true to preserve the existing sensor
behavior.
Existing width sensor G-Code commands are updated to optionally enable
and disable flow compensation and to show the state of the sensor and
command outputs are normalized.
Also includes updates to the relevant doc pages.

Add a new EddyParameterHelper to override ProbeParameterHelper.
Only use the printer.cfg lift_speed, samples, sample_retract_dist,
samples_result, samples_tolerance, and samples_tolerance_retries
settings for normal probe operations. Don't use these defaults when
using a "METHOD" set to "scan", "rapid_scan", or "tap". Each of these
probing mechanisms is distinct and it's unlikely a user could
meaningfully set a default for all of them.
Don't set sample_retract_dist when using "scan" and "rapid_scan"
modes.

Theoretically a "tap" probe should detect the exact point that the
nozzle contacts the bed. In practice, however, there can be a
systemic bias that one may wish to account for. This bias may be due
to backlash, thermal expansion, a detection bias, or similar issues.
Add a new tap_z_offset config parameter to allow users to specify an
offset.
Also, update the Z_OFFSET_APPLY_PROBE command to support modifying
this value.

The config option 'z_offset' name is confusing as its behavior is
notably different from how other probe hardware uses 'z_offset'.
Rename to 'descend_z' to make its behavior more clear.

Allow the "tap_threshold" to be overriden during PROBE type commands.
This makes it easier to calibrate an initial tap_threshold.

This adds host and firmware support for the Bosch BMI160 IMU. It includes support for both SPI and I2C communication protocols.
The firmware implementation includes a specific SPI wake-up sequence (dummy read) required to switch the sensor interface mode reliably. Validated on Linux MCU (SPI) and RP2040 (I2C) with stable 1600Hz ODR.

Added a temperature sensor configuration for ADS1103, ADS1104, ADS1105, ADS1113, ADS1114 and ADS1115 chips that can be used to add Analog to Digital Conversion capability to machines that don't have that on their own. Like Raspberry Pi's or if more analog input pins are needed than the chip provides like for RP2040. Generally they can be used for any analog input, but the typical use case is for temperature measurement. This code also has been written with temperature measurement in mind and not as a general ADC.
