OR: GS1CompanyPrefix does not uniquely identify a company

[a-stacey]

Many companies can share a single GS1CompanyPrefix and a company may be assigned multiple GS1CompanyPrefixes, the OR relies on this and so the design should be changed to fix this issue.

@paulsamways mentions that GLN's should be able to be used to uniquely identify companies, but we don't have the exact ref to hand atm.

One ref from @paulsamways

A Party (or) Location is any legal or physical entity involved at any point in any supply chain and upon which there is a need to retrieve pre-defined information. A Party is uniquely identified by a Global Location Number (GLN)
