Problem with the rmt_nec_tx_rx example.

1. This isn't really new example, but one that comes with esp-idf release. I noticed the rmt_nec_tx_rx example fills the rmt_items in the wrong order. I was testing the tx output with an arduino ir receiver and noticed the addr and cmd are going backwards. Either the mask (and the shifts) or the filling order need to be modified so you can get a working ir led output.

Hi:
What's arduino infrared lib do you use, can you give me a linkage? and post the result of arduino ir receiver?
The nec protocol used in example "rmt_nec_tx_rx" is standard, for more information you can refer to https://www.sbprojects.net/knowledge/ir/nec.php
