[Feature request]: Allow Puppet's Faces CLI to show multiple copyright holders

[jstraw]

Use Case

With the start of OpenVox, we need the ability to show both the legacy Puppet/Perforce and updated OpenVox copyright attributions. The Faces API doesn't allow for the data to be in a format that contains multiple copyright holders.

Describe the solution you would like

It would make sense to both reduce duplication and reach the goal of the use case, so I propose:

• Centralize the copyright attributions in the Faces code
• Convert that copyright attribution to allow multiple copyright holders and date ranges for those copyrights
• Sync all of the dates to the earliest starting date, and turn them from an singular year to a date range.
