Propose and implement an escape sequence for draggable files

[valpackett]

Imagine if we could just drag files out of ls output or a file manager like ranger and drop them into other applications…

That actually doesn't seem hard to implement. All that requires is a sequence similar to the "current directory" one, but with an end block (so it would apply to a particular string between start and end sequences). Programs like exa, lsd, ranger would be modified to emit those sequences. Then in the terminal just detect drag out of those marked cells and do a d&d offer with the provided path.

I might prototype this sometime in the future :)

FWIW, I think the OSC 8 hyperlink sequence is probably sufficient for this, in terms of escape sequences, and programs are already supporting it (eg: ls --hyperlink in reasonably recent GNU ls) for clicking and opening file:// URIs.

I think it would be a logical extension to allow dragging a cell with a hyperlink. Some folks have already requested drag and drop in the opposite direction in #640
