`cargo test --package ssi-vc --all-features` is missing some test vectors

[vdods]

The command cargo test --package ssi-vc --all-features produces errors regarding missing test vector files (output truncated for clarity):

I think it's just a matter of having forgotten to commit these files.

They are submodules, you need to run git submodule init --update
