## Usage

```rust
use rx8900::RX8900;

let i2c = /* ..i2c provider */
let mut delay = /* ..delay provider */

// initialize the RX8900 using the primary I2C address 0x32
let mut bme280 = RX8900::new_primary(i2c);

// initialize the rtc
bme280.init().unwrap();

// some delay
delay.delay_ms(10);

// set initial date time
let datetime = NaiveDateTime::new(
    chrono::NaiveDate::from_ymd_opt(2001, 2, 3).unwrap(),
    chrono::NaiveTime::from_hms_opt(4, 5, 6).unwrap(),
);
rx8900.set_datetime(datetime).unwrap();

// read date time from RX8900
let datetime = rx8900.datetime().unwrap();
