feat: add basic support for CDX 1.5 (#488)

This PR introduces basic support for CDX 1.5.

Ref: 
- #404

**Schema:** 

- Extended schema-downloader and added specification files, 
- Adapted `README` and `SchemaVersion` for 1.5

**Model:** 

- Added `SchemaVersion1Dot5`, serializable annotations, 
- Extended `ComponentType` and `ExternalReferenceType` enums

**Tests:** 

- Generated snapshots for 1.5. 
- In some existing tests `bom-ref` changed, since 1.5 is now listed before 1.4

**Chore:**

-  Added `newline = '\n'` to schema-downloader and `writeSnapshot` for cross-platform support
