This includes empty stubs for most core Arduino functions. Need to actually implement all those digital reads writes whatever. Need to prebuild toolchains (xtensa-elf-lx106) for 3 platforms and put them on some download server. Need to do the same with esptool. Need to fix 0x40000 binary generation and add correct upload commands. Maybe even implement uploads over WiFi.
