dev/optional component flag

[jkowalleck]

in reporting you can find

• "dev": true -- only omit with "dev"
• "devOptional": true -- only omit with "dev" AND "optional"
• "optional": true -- only omit with "optional"

this could be taken into the resulting SBOM.
either as properties, or as component.scope=optional -- https://cyclonedx.org/docs/1.4/json/#components_items_scope

since a property for development already exists, it this part is done.
but the "optional" part is lacking.

---

devOptionsl are both, optional and devDeps - at the same tme.
therefore they shxould et the property , and a sope et to "optional"

there should be an example created, that has the optionals shown.
