Add a flag -a to show all verification conditions sent to the smt solver

**Problem**
When there is an error we can use `-d` to get more info. But when there isn't an error, and there should be, we also should be able to see more information than just "Correct! Passed verification" if we want to.

**Proposed solution**
Similar to debug logger, add info for every smt query that has been done.

**Alternatives considered**
Always showing everything is too much, using interactive debug is the current option but not the best
