returns first (canonical) name when metaparameter is assigned a table of names returns name when metaparameter is assigned a single name returns empty string when metaparameter name not found in alias_src{}, id_src{}, or id_src[meta].custom_access

metaparameter is the key in Module:Citation/CS1 aliases{} table or id_handlers{} table. Because access-icon don't have keys, per se, we create pseudo keys by appending 'access' to the identifier : the for |doi-access= is, for the purposes of this function, DOIaccess, etc

Some lists of aliases might be better served when a particular alias is identified as the canonical alias for a particular use case. If, for example, Perodical lists: 'journal', 'magazine', 'newspaper', 'periodical', 'website', 'work' that order works fine for documentation but doesn't work so well for, , or. So, for using this function to document the returned value should be the parameter best suited for that template so we can specify magazine in the override (frame.args[2])

While for this function, it would be just as simple to not use the function, this mechanism is implemented here to match similar functionality in alias_names_get (there are slight differences) must exist in the alias list does not apply to the access icon parameters (ignored - these have no aliases)

(and which would be best for ? |newspaper= or |work=? can't solve all of the worlds problems at once).
