Complete support for CycloneDX v1.4

[madpah]

The following items are not currently supported for CycloneDX v1.4 (as of release 6.4.x):

• Missing compositions on Bom
  see via feat: support Bom.compositions #607
• Missing properties on Bom
  • see [FEAT] Add support for arbitrary properties at the BOM level (bom.properties) #125
  • Support in v1.4
  • Support in v1.5+ via feat: support bom.properties for CycloneDX v1.5+ #585

Any reason you removed labels for 1.5 and 1.6 @jkowalleck - as these items are also missing from those versions?

Any reason you removed labels for 1.5 and 1.6 [...] ?

the issue is rooted on schema 1.4 - so this is the only label relevant for this.
of cause, all later schema versions are effected :-)
