INPUT and OUTPUT are not 0 and 1 for all supported architectures

[soundanalogous]

I discovered this while attempting to support ESP32 boards. In the arduino-esp32 library, INPUT and OUTPUT are defined as 1 and 2 instead of 0 and 1 (as typically found in Arduino.h).

To resolve, PIN_MODE_INPUT and PIN_MODE_OUTPUT should be used instead of INPUT and OUTPUT in StandardFirmata variants as well as in ConfigurableFirmata. The issue is here and here in StandardFirmata for example.
