Enable similar behaviour under `GNU screen`

[n0542344]

While the current version of rvisidata supports tmux, this is not the case for GNU screen (the other, older terminal multiplexer).

From my understanding, GNU screen-support should also be possible using the following commands in a script with the following options in the function options(rvisidata.tmux = "path/to/your/script"):

• screen -X split to create a (horizontal) split.
• screen -X screen -t rvisidata bash to create a new split running bash.
• screen -X focus && screen -X prev to open the current window on the bottom split.
• screen -X at rvisidata stuff "vd\n" starts vd in the rvisidata-window (technically: stuff the string "vd" to rvisidata and then run Enter).
• screen -X focus gets the focus back to the vd-pane

Also it should be possible to find out if you're running in a screen-session by looking at the $STY-variable (unset if not, returns the session-name if it is).

Any chance to add screen-support in the future? I'd also support you in any way if you're interested.

Sound idea.

I'm currently prepping the code for a CRAN release. Let's work on this once I finish cleaning up the project.

No problem, I'm not in a rush.

If I can support you in any way just write!
