A definitive PicoFly install guide V.6.4

I wanted to make it clear that the RGB LED mod does in fact require an RGB LED to be added for the mod to work. The existing LED for the Nintendo Switch home button is just a simple blue LED.

Hopefully this will be the last update for a little while...

Basically everything in the guide remained the same, I just added Rear mosfet mounting and the aesthetic home button LED mod to the end of the guide. I also got rid of mentioning the color of the LED in the original flashing process. It should flash once quickly on successful flash, but when you power it up a second time, you will get glitch codes (or two short pulses, a pause, two more short pulses, a pause, and two final short pulses if your board is hooked to nothing but power)

- Rehius added new LED codes, and it seems like that's all that will be added?... for now
- Revamped the Switch Lite diagram with the graphic from http://balika011.hu/switch/lite/
- Added pinouts for RP2040-Tiny and Raspberry Pi Pico
- Added a warning about the RP2040-Tiny for people to check the resistance of the included resistors
- Added notes that GND points can be soldered to any ground on the board.

Updated the New LED codes to NEWER LED codes that include a short yellow flash to indicate glitch success.

Just a few tweaks to update to the newer firmware LED codes. I have removed the OLD LED codes in an effort to get people to download the latest firmwares, but I fear we are just going to end up with more posts saying "Why is my LED flashing pink/green/red?" We'll see...

Alien Retro Gaming got copyright striked for several of his switch hack install videos, including the one linked in the guide to the DAT0 OLED adapter install.

I decided to replace the link with one to a sthetix video. Maybe this one will be more resilient.

I figured out how to post the full V.4 guide in one pdf file, without breaking links, or text selection, or zooming clarity! Now there's basically just two really long pages that have been merged together.

There were a few things added, check the changelog.
