carphelp supports only CARPUTILS_SETTINGS
Problem to solve with the new feature
bin/carphelp
requires environment variable CARPUTILS_SETTINGS
to be set, but users might have set their settings.yaml
somewhere.
Proposal
Also check other possible locations of carputils settings.yaml
which carputils supports.
