chore: Release ds323x version 0.6.0

The method receives in decimal the value to be set as the day of the month, but the ds3231 module expects it in bcd format.  
Using the 'write_register_decimal' method, can be written in the correct format.

+## Usage
+
+To use this driver, import this crate and an `embedded_hal` implementation,
+then instantiate the appropriate device.
+In the following example an instance of the device DS3231 will be created.
+Other devices can be created with similar methods like:
+`Ds323x::new_ds3234(...)`.
+
+Please find additional examples using hardware in this repository: [driver-examples]
+
+[driver-examples]: https://github.com/eldruin/driver-examples
+
+```rust
+use ds323x::{DateTimeAccess, Ds323x, NaiveDate, Rtcc};
+use linux_embedded_hal::I2cdev;
+
+fn main() {
+    let dev = I2cdev::new("/dev/i2c-1").unwrap();
+    let mut rtc = Ds323x::new_ds3231(dev);
+    let datetime = NaiveDate::from_ymd_opt(2020, 5, 1)
+        .unwrap()
+        .and_hms_opt(19, 59, 58)
+        .unwrap();
+    rtc.set_datetime(&datetime).unwrap();
+    // do something else...
+    let time = rtc.time().unwrap();
+    println!("Time: {}", time);
+
+    let _dev = rtc.destroy_ds3231();
+}
+```
+
+## Support
+
+For questions, issues, feature requests like compatibility with other devices and other
+changes, please file an
+[issue in the github project](https://github.com/eldruin/ds323x-rs/issues).
+
+## Minimum Supported Rust Version (MSRV)
+
+This crate is guaranteed to compile on stable Rust 1.75 and up. It *might*
+compile with older versions but that may change in any new patch release.
