This PR further rework checksum.rs to get rid of entangled variable processing.

It also partly fixes #6576, for the case where the digest has an odd length (it may still fail in case the length is even but still wrong)

A (pedantic) detail: I would use == for better readability and swap the if and else parts.

There are two minor details, otherwise it looks good :)

- Rename the function to emphasize its goal
- Do not pass the filename anymore, as it is only used to create an error, that may be done in the scope calling the function
- Change the return type to Option, as the error is made in the outer scope
- Don't try to decode the base64 string as UTF8 string. This most oftenly fails and is wrong.
- Get rid of the `bytes_to_hex` function, as it provides the same functionality as `hex::encode`
- Add comments to explain what each field is counting
