FlashForge 2016 LCD/SDCard/Keypad Interface Board Redesign

See this thing on GitHub: [https://github.com/dewhisna/LCDInterface_FFCP](https://github.com/dewhisna/LCDInterface_FFCP).

I'm tired of having SDCard read issues on my FlashForge Creator Pro 2016 printers. I have three of those printers and all three have issues. After digging through and analyzing the schematics, I think the primary culprit is either ringing or a slight timing skew between the SCLK timebase and the unbuffered MISO data output from the SDCard. SDCards aren't designed to drive their data output down a 300mm ribbon cable.

Then if you add the other issues of no bypass capacitors, limited decoupling capacitors, no ESD protection, long off-board 3.3V power runs, and abuse of a 74AHC125 as a voltage level translator, it's a wonder, as Gary described with his [LCD ESD Protection board](https://www.thingiverse.com/thing:91656), "that it works at all".

I originally looked at just building one of [Gary's LCD ESD Protection boards](https://www.thingiverse.com/thing:916
