Trsh Orca auxilliary basis demand

[Lilachn91]

Describe the bug
ARC tried to trsh the following error in Orca "For DLPNO calculations we need at least one auxiliary basis set" using method 'change_node'.

How to reproduce
Orca input and output file attached, need to add to auxiliary basis '/c' at the end.
input.txt
output.txt

Expected behavior
ARC should alert the user of a problematic basis set, and then gracefully terminate.

thanks @Lilachn91!
Why should we terminate and not choose an appropriate basis set for the user?
