20250721: The `[pca9632]` module no longer accepts the `scl_pin` and
`sda_pin` options. Use `i2c_software_scl_pin` and
`i2c_software_sda_pin` instead.
20250428: The maximum `cycle_time` for pwm `[output_pin]`, 20250428: The maximum `cycle_time` for pwm `[output_pin]`,
`[pwm_cycle_time]`, `[pwm_tool]`, and similar config sections is now 3 `[pwm_cycle_time]`, `[pwm_tool]`, and similar config sections is now 3
