Implementations on Foreign Types

impl StorageAppend<DigestItem> for Digest

We abuse the fact that SCALE does not put any marker into the encoding, i.e. we only encode the internal vec and we can append to this vec. We have a test that ensures that if the Digest format ever changes, we need to remove this here.
