feat: Add support for new Copyrights and schema updates

### JSON Schema
- **Added**: New JSON schema version `16.0.16` with support for the new `Copyrights`.
- **Modified**: Updated the `JSONSchemaVersion` parameter to use the new schema.

### Package Structs
- **Added**: New `Copyrights` field to the `Package` and `PackageBasicData` structs, similar to the existing `Licenses` field.
- **Added**: New `Copyright` struct.
- **Implemented**: Sorting methods for the `Copyright` struct.

### toPackages Function
- **Changed**: Updated the `PackageCopyrightText` to use `helpers.GetCopyrights(p.Copyrights)`, which formats the copyright text and returns a string. Example output: "Copyright 2014-2014 Matt Zabriskie & Collaborators".

### toSyftPackage Function
- **Added**: `Copyrights` assignment to the `toSyftPackage` function.
