HX711 library notes

Backlog

• [o] Get library into https://www.arduinolibraries.info/ and https://platformio.org/
• [o] Maybe use constructor-based initialization again? It does not necessarily need to starting talking to the hardware yet!
• [o] Unify critical sections / interrupt disabling between platforms? https://github.com/esp8266/Arduino/issues/2218
• [o] Check out https://github.com/mmarchetti/DirectIO

• Q: Would delay(1) be better than delay(0)? A: even delay(0) will work. Should be as often as you can spare, but not more than 100ms let's say -- https://github.com/esp8266/Arduino/issues/2240#issuecomment-230874704
