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

Register an event handler to make sure measurements are stopped if a
gcode error occurs while using EddyScanningProbe. EddyTap and
EddyDescend use ProbeSessionHelper which already provides this
handling, but EddyScanningProbe doesn't use that wrapper so it must be
implemented manually.

Increase ADC report time from every 15ms to every 10ms and batch every
5 reports into a single message. This should improve the
responsiveness and reduce the communication overhead when using ADC
buttons.

Change the get_last_value() method to return time first then value
(instead of value, then time). This makes get_last_value() match the
order of parameters that is used in the adc update callback.
This also fixes ads1x1x to return the "print_time" instead of a system
time.

Replace the integer values of STOP_ON_ENDSTOP with string values and
deprecate the older format. The newer string values should make the

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.

Commit 2a1027ce changed the "probe:update_results" event to take a
list, but failed to update the callers to utilize that modified list
in its results.
Change axis_twist_compensation to update all members in the list and
change the callers to use the resulting list.

There are some rare corner cases where reporting the peak time could
cause hard to debug issues (for example, the peak time could
theoretically be a significant time prior to the actual trigger time,
which could possibly cause unexpected clock rollover issues). Now
that the host code does not utilize the peak time for "tap" detection,
it can be removed from the mcu code.

To cancel out any lag, filter data on the host
Then to avoid derivatives lag,

To implement host-side analysis of tap data,
we need a way to apply the same filtering as on the mcu.
As bonus, it cancels the induced signal delay.

Don't require callers of MCU_trigger_analog to create the
mcu.TriggerDispatch() instance - instead, create it within the
