The Subinitial Stacks Python library provides a consistent way to specify indices when calling functions or class methods. There are generally two ways to specify indices:

An arbritary set of each integer index can be passed directly, e.g.:
```
core.leds.set(0, 1)  # This turns on Core User LEDs 0 and 1
```

A bitmask of indices can be passed with the mask parameter, e.g.:

core.leds.set(mask=0b11)  # This turns on Core User LEDs 0 and 1

Warning

Use EITHER an arbitrary set of integer indices OR a bitmask BUT NOT BOTH
