Allow Shell Access from SuperFile

Felt like this deserves a fresh discussion so I made a new issue.

I will add use / or some other key to open a line of command input at the bottom to replace this function.

@MHNightCat Was this added? It was the first thing I looked for when trying Superfile today.

I use TMUX, but that doesn't mean a quick way to execute commands isn't welcome, especially if there's a way to automatically include selected files in the Visual selection mode. ( e.g / <command> {} )

The file manager nnn (n³) (18K stars) has this sort of feature, for reference. You can launch a shell in the PWD or enter a command in a prompt, as well as a very useful "cd on quit".

Midnight Commander, an old (90's) but still very relevant and well known TUI file manager, also features a command-line at the bottom approach.

As does Ranger with :shell <command>. (15K stars)

This hasn't been done yet, but I haven't given up on the idea.

Fair enough, and no pressure. I just wanted to add my support.

Compared to the above options, I really like the look and layout of Superfile, especially the simultaneous multiple panes. Nice work.
