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.

Keeps the width sensor state in sync with the associated runout sensor and
normalizes the output when the width sensor is disabled.
When the width sensor was disabled the associated filament sensor remained
enabled but was no longer updated so would be 'stuck' in the last state it
was in before the width sensor was disabled.
The toggle switch and readings in the web interface could also be out of sync
with the actual sensor and filament states, misleading the user.
Now, when the width sensor is disabled:
- The filament sensor is disabled
- The reported filament state is 'present'
- The reported filament diameter is the nominal diameter
When the width sensor is enabled:
- The filament sensor is enabled
- The reported filament state is the derived state
- The reported filament diameter is the measured value
Finally, `min_diameter` is now used to determine the runout state rather than
a fixed value of `0.5`.

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.

This adds host and firmware support for the Bosch BMI160 IMU. It includes support for both SPI and I2C communication protocols.

Deprecate the PROBE command's exported value
`{printer.probe.last_z_result}`. This value effectively returns the
toolhead Z position when the probe triggers and user's then need to
adjust the result using the probe's configured z_offset.
Introduce a new `{printer.probe.last_probe_position}` as a
replacement. This replacement has an easier to understand behavior -
it states that the probe hardware estimates that if the toolhead is
commanded to last_probe_position.x, last_probe_position.y and descends
then the tip of the toolhead should first make contact at a Z height
of last_probe_position.z . That is, the new exported value already
takes into account the probe's configured xyz offsets.
