feat: Optional dependencies

[jkowalleck]

fixes #645

---

• Added
  • SBOM result might have component.scope=optional populated for OptionalDependencies
• Fixed
  • DevDependencies that are also required by OptionalDependencies correctly have the property cdx:npm:package:development populated in SBOM results
  • DevDependencies that are also required by OptionalDependencies are correctly omitted from SBOM results, when the CLI switch for omitting "dev" and "optional" are set
