An embedded-hal driver for the GP2D12 infrared distance sensor.
Distance calibration is based on the values in the
[datasheet](https://media.digikey.com/pdf/Data%20Sheets/Sharp%20PDFs/GP2D12.pdf).
## Examples
```rust
use gp2d12::Gp2d12;
// 3300 mV max voltage on the ADC, 12-bit precision
let mut gp2d12 = Gp2d12::new(pin, 3300, 12);
// measuring 40 cm
assert_eq!(gp2d12.distance(&mut adc), Ok(Some(40)));
```
