Add ability to configure alarms for INT pin #12

I see this described as follows :

INT - Interrupt signal out, you can set this up to pull low when the voltage or percentage drops below a threshold. Pulled up to VIN with a 10K resistor

Does this automatically trigger when IC senses battery too low, or is this programatically triggered ?

EDIT -

From Datasheet appears to be be written at 1 of 2 registers, but doesn't appear as though library enables this

hi this isnt a bug report, tech support is handled in the forums. thanks :)

Reopening and changing title to better reflect issue. This library is missing functions to set registers 0x13 and 0x14 which control the INT pint behavior.

I'm starting to look at this during the PyCon US 2023 sprints.
