got unknown checksum type SHA512

[mwestphal]

When working with spdx file provided by https://github.com/kubernetes-sigs/bom, I have this error. Removing the checksum fixes it but it would be better to not need manual intervention on the files.

Example file:
b.spdx.txt

Hi @mwestphal , this is a bug in tools-golang which should be fixed with 0.4 planned for Dec 31st.
