Abracon AB-RTCMC-32.768kHz-IBO5-S3 RTC implementation for NervesTime

To configure NervesTime to use this module, update the `:nerves_time` application
environment like this:

```elixir
config :nerves_time, rtc: NervesTime.RTC.Abracon.IBO5
```

If not using `"i2c-1"` or the default I2C bus address, specify them like this:

```elixir
config :nerves_time, rtc: {NervesTime.RTC.Abracon.IBO5, [bus_name: "i2c-2", address: 0x69]}
```

Check the logs for error messages if the RTC doesn't appear to work.

See https://abracon.com/Support/AppsManuals/Precisiontiming/Application%20Manual%20AB-RTCMC-32.768kHz-IBO5-S3.pdf
for implementation details.
