warning "legacy timer group driver is deprecated, please migrate to driver/gptimer.h"

[duinzicht8]

Dear Tjerreio,

This is an error with the esp-idf latest.
The older version was imcompatable with the atest updates UBUNtu 2022.4.
So I tried the esp-idf latest.

I am not prepared to dig into this just now, can you do it and submit a PR for the needed changes?
