Within the library you often throw a cancellation exception to cancel the scope/flow, but a more precise exception in the Result would be really appreciated, especially when known.

For example here in the readCharacteristic:

```
// TODO: throw precise reason if we can gather the info
else Result.failure(CancellationException("fail"))
```

but also in other places.

Thanks.
