- If enabled, esp_timer_dump will dump information such as number of times the timer was started,
- number of times the timer has triggered, and the total time it took for the callback to run.
- This option has some effect on timer performance and the amount of memory used for timer
- storage, and should only be used for debugging/testing purposes.

- Configure the stack size of "timer_task" task. This task is used
- to dispatch callbacks of timers created using ets_timer and esp_timer
- APIs. If you are seing stack overflow errors in timer task, increase
- this value.
- Note that this is not the same as FreeRTOS timer task. To configure
- FreeRTOS timer task size, see "FreeRTOS timer task stack size" option
- in "FreeRTOS" menu.

- esp_timer APIs can be implemented using different hardware timers.
- - "FRC2 (legacy)" implementation has been used in ESP-IDF v2.x - v4.1.
- - "LAC timer of Timer Group 0" implementation is simpler, and has smaller
- run time overhead because software handling of timer overflow is not needed.
- - "SYSTIMER" implementation is similar to "LAC timer of Timer Group 0" but for ESP32-S2 chip.
