In this PR:
formatsused by thesyftpackage to ensure that no formats panic when trying to decode or validate an empty SBOM.nilcheck to the SPDX document processing logic.Additionally, for convenience, I implemented
fmt.Stringeron theformat.IDtype for use in string descriptions of format operations. This can be undone if needed!This prevents the panic shown in anchore/grype#693, but a separate Grype PR will catch the "empty SBOM" case even earlier to provide a more direct error message to the user. So this PR isn't strictly necessary with regard to anchore/grype#693, but it still fixes a panic case for the Syft library.
