extending the %jukit_run helper to other languages (Julia)

[benkj]

Same as title. It would be great, but I don't know if possible.

The problem with current workflow is that send#selection as a cut&paste is very slow when dealing with large cells and selections, at least in all terminals I tried (gnome,kitty,iterm).

I'm wondering if we can extend jukit_run to use it in other languages. Things I thought, though I don't know if they are possible

1. Run ipython instead of julia, and then run julia code from there using the juliacall package. Possibly the easiest option, but quite hacky
2. using IJulia.jl in some clever way. For instance, IJulia.magic_help already has some predefined 'magics', so perhaps they are easy to extend
3. Write a (small) julia package that handles jukit_run, but how?
4. simplest yet not as powerful: write the selection into a file, and then run include("file") into the repl

Any thoughts / help would be appreciated, as I'm not familiar at all with IPython's magics
