RMT code migration from ESP-IDF 4.2 to version 5.2.2

Thank you for your help, I think I understand the driver now.
We are using the TX config so set up the wavefrom generator where data bit durations and levels are applied from the array of rmt_words. Then for carrier we set up the desired freq and dc and this modulates the data waveform each time data level is "1".
