Basic usage - linux_embedded_hal example

```rust use mpu6050::*; use linuxembeddedhal::{I2cdev, Delay}; use i2cdev::linux::LinuxI2CError;

fn main() -> Result<(), Error> { let i2c = I2cdev::new("/dev/i2c-1") .map_err(Error::I2c)?;

let delay = Delay;

let mut mpu = Mpu6050::new(i2c, delay);
mpu.init()?;
    mpu.soft_calib(Steps(100))?;
mpu.calc_variance(Steps(50))?;

println!("Calibrated with bias: {:?}", mpu.get_bias().unwrap());
println!("Calculated variance: {:?}", mpu.get_variance().unwrap());

loop {
    // get roll and pitch estimate
    let acc = mpu.get_acc_angles()?;
    println!("r/p: {:?}", acc);

    // get roll and pitch estimate - averaged accross n readings (steps)
    let acc = mpu.get_acc_angles_avg(Steps(5))?;
    println!("r/p avg: {:?}", acc);

    // get temp
    let temp = mpu.get_temp()?;
    println!("temp: {}c", temp);

    // get temp - averages across n readings (steps)
    let temp = mpu.get_temp_avg(Steps(5))?;
    println!("temp avg: {}c", temp);

    // get gyro data, scaled with sensitivity 
    let gyro = mpu.get_gyro()?;
    println!("gyro: {:?}", gyro);

    // get gyro data, scaled with sensitivity - averaged across n readings (steps) 
    let gyro = mpu.get_gyro_avg(Steps(5))?;
    println!("gyro avg: {:?}", gyro);

    // get accelerometer data, scaled with sensitivity
    let acc = mpu.get_acc()?;
    println!("acc: {:?}", acc);

    // get accelerometer data, scaled with sensitivity - averages across n readings (steps)
    let acc = mpu.get_acc_avg(Steps(5))?;
    println!("acc avg: {:?}", acc);

} ``` Note: this example uses API of version on local master branch. Some functions may not be available on published crate yet.
