Support for ESP32 C6

[kaktus42]

Hi, as far as I understand, the ESP32 C6 does support I2S and RMT. However, in this library it is currently disabled because the interface changed (?). Am I understanding that right?

NeoPixelBus/src/internal/methods/NeoEspBitBangMethod.h

Lines 370 to 371 in fd670ee

	// Esp32 C6 && H2 currently use BitBang as the default until other support
	// is created, as they are not compatible with older generation chips

NeoPixelBus/src/internal/methods/Esp32_i2s.c

Line 25 in fd670ee

// ESP32 C3, S3, C6, and H2 I2S is not supported yet due to significant changes to interface

When I try to compile it with the RMT, I am (also) getting deprecation errors:

#warning "The legacy RMT driver is deprecated, please use driver/rmt_tx.h and/or driver/rmt_rx.h"

Are there already some thoughts on how an implementation of this lib for C6 could be done? I would be willing to try, but any help and though on how you would approach it to make it fit in the library design standards would be helpful.

Look at the Core3 branch. It supports the newer core and has some C6 support updated.
