led_strip Update for ESP-IDF v5?

[Xylopyrographer]

Hi all. Wondering if anyone is working on updating the RMT led_strip component to work with new RMT API's introduced in ESP-IDF version 5?

Been poking at this myself but cannot figure out how to implement the global brightness function as I cannot understand how, with the new API's, to intercept and modify the byte representing a pixel colour component (the R, G, or B value) before it is sent to the RMT symbol encoder. Anyone know how to crack that nut?
