Add the ability to display filament extruded, filament remaining, and total filament needed for the current print.

[lgeitner]

Hello,

I have not seen a way to add filament extruded , filament remaining, and total filament needed for the current print.

I would like to display on my printer a message similar to:

27.67m of 77.47m filament used

and

49.8m filament remaining

See my screen shot below from octoprint

Would this be possible to add in the future?

Thanks, Lance

If the information can be queried it could be added, but I do not have that hardware to test. Feel free to open a PR if you want to make updates.
