I use Inkscape so I am not familiar with those programs.
In inscape, you can “trace bitmap” then “brake apart” to get single lines. Here is it done that way in inkscape ad saved as an svg for you. I needs to be cleaned up some (lots of little fragments that can be removed.
This is going to be tough to cut out because each line is so close to each other. What I do in those cases, I go in and move the nodes around to widen all the narrow spaces, but don’t know how to do that in other programs, or what they even call those.
