trsh: scan_qualitiy_check

[NellyMitnik]

Describe the bug
I was running CBS-QB3 calculation for some species. The last species that appears in arc.log was this one: [O]C=CC=C=CO :
Species C5H5O2[43] is not oriented correctly around pivots [3, 4], searching for a better conformation...

Traceback (most recent call last):

Expected behavior
I expect that ARC can catch this type of error and skip the calculation for the problematic species.
