Getting the active spool in klipper?

[bofh69]

Instead of having the slicer add a custom gcode for setting the active spool, I want the gcode macro to verify that the right filament (or at least spool) is selected already. If not, pause and wait for me to load the right spool.

If I'm always using a gcode macro to set the new filament, it could also store it in a gcode-variabel and save the variable, but that won't work if I update the spool via moonraker.

Is it possible to get moonraker's active spool (and other info about the spool?) into a variable for a klipper gcode macro somehow?
