What is the maintenance status of this project?

## Description

In [`gh`](https://github.com/cli/cli), we've had a long outstanding [PR](https://github.com/cli/cli/pull/7743) to use this module for secure credential management.

Looking at the repo commit history, community interactions (or lack thereof), and [dependent forks](https://github.com/99designs/go-keychain), it's not clear to me what the maintenance status of this project is.

I totally understand that ongoing maintenance of a project like this is burdensome, and might not be something 99designs or individuals want to continue with, but I do hope y'all (maybe @mtibben?) can offer some guidance on what potential consumers of this project might be able to expect in the short term or long term?

Cheers!
