Support for GUITION JC4880P433 development board

[kanefron5]

It is a 4.3-inch capacitive touch display development board built around the GUITION JC-ESP32P4-M3 ESP32-P4 and ESP32-C6 module.

Hi. I was hoping to not add too many more platforms, but this one does look really interesting. The documentation for it it great.
I do want to learn more about the P4 series.
I have ordered one. I'm not sure how it will fit in with my code, but I will see how it goes.

I delved into capturing Tonex audio via USB and it looks like Tonex requires USB High-Speed protocol (480 Mbit/s), where ESP32-s3 can only do Full-Speed (12Mbit/s). But P4 has support for High-Speed, which would allow for implementing an onboard tuner, and maybe even some global eq that so many people on the internet wish Tonex had.

I did receive the P4 dev board and it does look very good.
I've done some initial investigations into what it will take to support the P4 on the project, and it is going to take some work.
I plan to get a release out soon with One Plus support and ESP-IDF 6, and then look at the P4 after that.

Regarding tuner, the One Plus has remote tuner support, where you can command it's state and the pedal streams back reference frequency, error in cents, and the Midi value of the nearest note. I was able to do an LCD screen for it and it works really well.
It's a shame IK haven't back ported this to the One (I did try to send the same message to the One but it was ignored.)
