Check whether it works with https://github.com/gizak/termui

FYI https://github.com/erroneousboat/slack-term/issues/262

If it works, we can consider packaging gizak/termui. See https://salsa.debian.org/go-team/packages/termui/-/issues/2

We need to check compatibility, which is better?

• plan a. package erroneousboat/termui and use it
• plan b. package gizak/termui and use it
