Panic: attempt to multiply with overflow

[tacuna]

When running the example i get

serial: [retracted]
Waiting for first measurement... (5 sec)
thread 'main' panicked at 'attempt to multiply with overflow', [retracted]/scd4x-rs/src/scd4x.rs:77:29

Seems like temperature: '((((21875 * temperature) >> 13) - 45000) as f32) / 1000.0' is not safe.

This seem to work and gives plausible results

    Ok(SensorData {
        co2,
        temperature: temperature as f32 * 175_f32 / 65536_f32 - 45_f32,
        humidity: humidity as f32 * 100_f32 / 65536_f32,
    })

Looks good, I will change it in the next few days.
