Clean up Lineage dependent methods from Query

[mpkorstanje]

🤔 What's the problem you're trying to solve?

Query exposes a lot of redundant methods that reduce or expose lineage.

✨ What's your proposed solution?

These could be done in client libraries, making the query more focused on querying. This keeps the API minimal, making other implementations easier. #81

Also: Consider making a diagram of all message relations and queries for that.

⛏ Have you considered any alternatives or workarounds?

Note to self: Write down the the purpose of the library in a bit more detail. In scope: Finding one message given another. Finding and processing lineages in the Gherkin document. Naming pickles.

Out of scope: Grouping elements by other elements.
