Fix import errors after swh-model update and move from PIDs to SWHIDs
Some functions in swh.model.cli
imported by swh-scanner
were renamed in
swh-model 0.3.8
leading to import errors, fix those.
Also rename references to persistent identifiers (doc, variables, function names) in order to use the SWHID abbreviation as this is what should be used now.
