The behavior enable by the PR is described on pages 11 to 14 of the DS3231 Datasheet. Two new methods are provided:

interrupt() - configures the INT/SQW pin to be activated for a specified alarm (0 or 1).
no_interrupt() - unconfigures INT/SQW pin activation for both alarms.

The documentation is updated to describe these methods and the library version is increased from 1.2 to 1.3.

We have merged this PR, however we are deprecating this library. We now only support CircuitPython. Please fork if you wish to continue development.
