BOM download should let users choose a CycloneDX spec version

[anthonymastreanvae]

Current Behavior

Downloading the BOM from a project created with a v1.6 format BOM is creating a v1.5 format BOM.

Steps to Reproduce

1. Create a project
2. Generate a v1.6 BOM with @cyclonedx/cyclonedx-npm or dotnet-cyclonedx
3. Upload the BOM
4. Download the BOM

Expected Behavior

I expect either...

• the latest BOM format to be supported
• the same BOM format that was uploaded (successfully) to be downloaded
• or to have a choice of which BOM format to download
