github.com/tarm/serial dependency dormant since 2018

I maintain the [Fedora package](https://src.fedoraproject.org/rpms/google-guest-agent/) for `guest-agent` in Fedora and it still has a dependency on `github.com/tarm/serial`. However, that [repository](https://github.com/tarm/serial) hasn't seen updates since 2018.

Would it be possible to use a newer, more recently updated dependency in the project instead? Thanks!
