This commit adds a predicate specification for CycloneDX using the example specification from issue #82.

The motivation for doing this is only to offer help with getting this into in-toto, in case the original author currently does not have time.

Thanks for this PR @danbev! Could you please make sure to write up your proposed predicate in ITE-9 formatting guidelines?

A separate question, how large do you expect CycloneDX predicates to be in practice? We do want to consider scalability of attestations as well.

Sorry about that, for some reason I though it was in that format. I'll take a look at this next week and update 👍

I'm afraid I don't know the answer to this question as I have very little practical experience with CycloneDX. Hopefully others can chime in that do have experience.

This should be good to go. It does reference the most up-to-date CDX schema as the predicate

Is it supposed to just be https://cyclonedx.org/bom? The page doesn't include the version (which I assume is embedded in the predicate field as it is for SPDX?

Thank you for the changes, @danbev !

One more thing: Could you please add a link to the CycloneDX spec in the predicates list?
