It's called quarter-plane-mode and is available from GNU ELPA.
But don't expect miracles from it.

The extra spaces should normally be deleted upon save, so they should
not make a difference except for display line-wrapping
(quarter-plane-mode uses the same technique of inserting&removing spaces
as needed; actually uses code from picture-mode internally).

Indeed, rectangle-mode has some code that does something related, but it
only handles the part of *displaying* the cursor where there's no actual
text, it doesn't try to let you then insert text at that position.
