ESP32 run's doom!

Finally!!! yay!!!! Added support for the prboom wad so it can run the original unmodified wads. Added support for ST7735R TFT. it&an old eBay special I had in the junk box; I could never get it running properly with Arduino libs, it still looks a bit dodge, I might buy a real one from core. :-). I wired it up to prove doom was actually working. TODO& - fix weird memory crash. - controller. - battery power - bigger screen - custom case and PCB. (I&thinking titanium would be a good fit for a handheld dedicated doom console). I love C, electronics and Doom! yay, perfect project! I&post code to GitHub when I&done. Share and enjoy.
