HD108 method using PARLIO peripheral on ESP32-C6

[tommag]

Hello,

Here is a method to use the new PARLIO peripheral in ESP32-C5 / C6 / P4 / H2 / H4

I have only defined it for the HD108 type yet but it should be pretty easy to adapt for other 2 wire LEDs, while freeing the SPI controller for other tasks.

I also fixed the generic HD108 method that had refresh issues.

Tested with an ESP32-C6 and HD108 LEDs at max 10MHz (but should work up to 40MHz).

Thanks for sharing your work and for the nice code architecture, I enjoyed adding features to the lib which is not always the case !

just some minor style updates needed

code style:
This library uses the "curly braces on their own line" format style.
While in general initialization (like this line) are often not strictly inforced, it more important for branching statements EVEN if they are single line (see below).

code style:
This library uses the "all code blocks require wrapping curly braces" and "curly braces on their own line" format styles.
so this needs to change to something like...

for (int i = 0; i < 16; i++)
{
            _wire.transmitByte(0x00);
}
