ESPNow was broken on ESP32-S3 as of the ESP-IDF v6.0.1 upgrade, and was failing on other boards earlier.

This restores it to working at least to some extent.

The new way to set the phy_rate is with esp_now_set_peer_rate_config(). However, this function is poorly documented (I opened espressif/esp-idf#18766), and the settings for the passed struct are not documented.

To fix this for now, I just commented out the ability to set the phy_rate, leaving it at the default 1Mbps. I added documentation to point out setting the phy_rate does nothing for now.

Also note that esp_now_set_peer_rate_config() should be called after esp_now_init(). It was being called before.

I tested with an ESP32-S3 broadcasting and and ESP32-C6 receiving, using the example code in https://learn.adafruit.com/esp-now-in-circuitpython/code-esp-now.

@todbot for interest.
