Add esp32s3 experiment

[AnthonyGrondin]

This makes the experiment run on esp32s3.
esp-hal is currently patched until a new version is released that contains the fix in: esp-rs/esp-hal#616
esp-wifi uses commit from esp-rs/esp-wifi-sys#205 to test on the latest revision

TODO

This currently gives me a borrow error in esp-wifi, which still needs to be figured out.

esp32c3-dhcp-experiment/dhcp-experiment-esp32s3 on  esp32s3-experiment [!] is 📦 v0.1.0 via 🦀 v1.70.0-nightly

Tested with an Android phone as the client

[AnthonyGrondin]

I've done a bit more testing, and it seems to work well when compiling in release mode. The error seems to happen only when compiling in debug mode.
