- support range based for loops
 - add remove() method to remove a node
 - add clear() to empty entire list and delete nodes
 - add empty() helper

   This adds an optional default support for HW that does not
   have and external armed indiction.

Move member variable initialization out of the constructor list to variable declarations, format whitespaces/tabs in sf1xx.cpp.

- Accel: use cutoff of 62.5 Hz instead of 500 Hz
- Gyro: the cutoff frequency is coupled with the ODR and is fixed to 116 Hz
  at 1 kHz readout rate. So this patch does not change anything for the
  gyro.

Because BATT_SMBUS is using a different structure (the ModuleBase class), and `BATT_SMBUS::task_spawn` is only called for the `start` command. This is the reason why you don't need to check for it in here.

using only <px4_getopt.h> as include, cleanup related includes
added check that all the option are valid (myoptind >= argc). if there are invalid options on some script that might now lead not to run commands

Rate changes were doing an asynchronous register reload via the EGR_UG. This could extend a PWM pulse up to 2X.

This fix removes the asynchronous update. The net effect is the the rate change will occur on the next counter expiration. The worst case is the rate change is delayed by 20 Ms.

Fixes regression from https://github.com/PX4/Firmware/pull/11216.
