Normalize person fields of a codecheck.yml to lists of persons

The spec requires `codechecker` and `paper$authors` to be lists of persons, but a single person is often written as a plain mapping, which yaml parses into a named character vector instead of a list of lists. Wrap such cases so consumers can always iterate over persons and use `$name`/`$ORCID`.

Usage

normalize_person_lists(config_yml)

Arguments

config_yml

the parsed codecheck.yml, may be NULL

Value

the codecheck.yml with normalized person lists
