Unify to one single Address class

Addresses used by gleif do not match schema.org... so we we have multiple address formats now.

@VladimirAlexiev:

• The best would be for Traceability to use one definition of Address, rather than conflicting definitions from several ontologies. This means to collect address props from all relevant ontologies.
• This pertains to the class as well (s:address vs LEIaddress mapped to https://www.gleif.org/ontology/Base/PhysicalAddress)
• The whole concept of address lines is obsolete when you can use newline in a string. A single field https://schema.org/streetAddress is better.
