i'm checking a data_ready bit through i2c, the sensor have 200, 100, 10...Hz modes,
```
    pub fn check_data_ready(&mut self) -> Result<(), Error<E>> {
        let mut retries = 2;
        while retries > 0 {
            let status = self.read_register(Register::ST1)?;
            if (status & 0x01) != 0 {
                return Ok(()); // Data ready
            }
            std::thread::sleep(self.mode.into());
            retries -= 1;
        }
        Err(Error::DataNotReady)
    }
```
is better than:

```rust
    pub fn check_data_ready(&mut self) -> Result<(), Error<E>> {
        let mut retries = 100;
        while retries > 0 {
            let status = self.read_register(Register::ST1)?;
            if (status & 0x01) != 0 {
                return Ok(()); // Data ready
            }
            retries -= 1;
        }
        Err(Error::DataNotReady)
    }
```
