Description

**Describe the problem you have/What new integration you would like**

I understand supporting this should not be a priority over other useful sensors, but having support for some kind of reliable I2C RTC chip would be nice in certain situations, especially if the ESPHome node is placed at a location where the wifi signal strength is poor.
**Please describe your use case for this integration and alternatives you've tried:**

Without a bulky external antenna, GPS modules don't work that well in some buildings, sometimes it won't even get a fix at all.
**Additional context**
