wip version 3

[kwrooijen]

Most notable: Replaced get-terminal with text-terminal.

Still need to look at a few things that have changes in lanterna. I've commented those out to make it compile.

This works in bb:

(require '[lanterna.terminal :as terminal])

(def terminal (terminal/text-terminal))

(terminal/start terminal)
(terminal/put-string terminal "Hello TUI Babashka!" 10 5)
(terminal/flush terminal)

(Thread/sleep 1000)
