execution: rework binary operators, add set operatos

[MichaHoffmann]

• rewritten binary operators ( really no good reason; it just kinda happened )
• added support for "and, or, unless" ( prepared support for native histograms but that will be followup )
• fixed some bugs in our duplicate label detection logic
• fixed minor bug in error reporting for hash collision on left side in a one-to-one matching
