Different mapping options

[kothique]

sensor.initialize({
  // ... options along the way,
  mapping: 'physical' // 'gpio', 'bcm', 'wiringPi' could be supported for example (bcm === gpio)
});

The default option would be 'gpio' for compatibility.
Also I don't know if it should be done on JS or C++ side.

I like the idea. I'd prefer to have the mapping done in the JS layer. I'd like to avoid growing the C/C++ layer unless there's a good reason for it (e.g. performance, low-level GPIO access, etc).

Agreed.
