tmux support for Linux
**tmux Support for Linux**
The `run` script with `cos_117.cfg` spawns xterms for consoles, which works well on desktops but not on VPS/servers without X forwarding or for users preferring SSH/shell/mosh.
To resolve, this commit adds tmux support via:
+ run_tmux - Script that manages a cray simulator session.
+ cos_117_tmux.cfg - Modified config that spawns tmux windows instead of xterms.
Benefits:
- Organizes cray simulator and consoles as tmux windows in a tmux session.
- Allows attaching, detaching, and exiting without stopping the simulator.
- Console windows can be scripted to pass input / output for development.
Usage:
```
run_tmux start
run_tmux attach
or execute `run_tmux` and select from menu.
```
Full Usage:
```
Usage: run_tmux {start|stop|restart|kill|attach|status}
start - Start the Cray simulator session
stop - Stop the Cray simulator session
restart - Restart the Cray simulator session
kill - Kill the Cray simulator session (unsafe)
attach - Attach to the Cray simulator session
status - List running Cray simulator and consoles
Use keys 'Ctrl b <0 to ...>' to move to specific windows
Use keys 'Ctrl b n' to move to the next window
Use keys 'Ctrl b p' to move to the previous window
Use keys 'Ctrl b d' to detach from the simulator session.
```
Tests:
- The script was checked in shellcheck with minimal issues detected.
- Tested on Ubuntu 22.04.3 LTS (aarch64)
- Tested on Arch Linux (x86_64)
