Improve handling when missing config file

Attempting to test the new pppp functionality to upload a gcode produces the following error

I'm 90% positive this error is because I didn't run ankerctl config show first (I don't see a default.json file present in ~/.config/**)

./ankerctl.py config show
[E] No printers configured. Run 'config import' to populate.

Solution

Catch missing config files and give a human readable instruction to run the config import first

 ./ankerctl.py pppp print-file --no-act /Users/spuder/3dprints/ender2pro/predynasticvase_1d1h24m_0.08mm_245C_PETG_ENDER2PRO.gcode
