Can you add a test case here that proves this change fixes the issue?

The idea would be to do something like change sbom-formats = ["application/vnd.cyclonedx+json"] to sbom-formats = ["application/vnd.cyclonedx+json;charset=us-ascii"]. I don't know if that's valid, but I'm pretty sure that will fail using the current methods. Because it will detect the media type as one of these options (https://github.com/buildpacks/libcnb/blob/main/layer.go#L96-L101), which don't match exactly.

Hi @sagnik3788, just wanted to follow up and see how things are going. Did you see my previous note? Are you still interested in submitting a code change here? Thanks!

Closing as we need some test coverage to be able to merge this. @sagnik3788 if you want to pick this back up feel free to send a new PR. Thanks
