Fix digest continuation bug

[rmja]

The digest should not continue to lower priority cases if the parser returns incomplete.

This fixes #140

[MathiasKoch]

This is a nice catch!

Could you fix the clippy CI, so I can merge it?

[rmja]

cargo clippy does not show anything on my machine. Can you trigger CI to re-run?

[MathiasKoch]

It runs with -- -W clippy::all -W clippy::pedantic -W clippy::nursery -W clippy::cargo in CI

[rmja]

From the CI details I get "Error: Unable to create clippy annotations! Reason: HttpError: Resource not accessible by integration". It seems unrelated to the PR?

[MathiasKoch]

I think this is what it fails on:

@MathiasKoch it seems happy now:-)
