Add functionality to build arenas for new paper (Zinck, Ricker 2020)

[gzinck]

• Implement transducer T₀, which adds a tau after every ∆ events
• Implement transducer T₁, which separates events and communications
• Implement transducer T₂, which propagates delay up to the clock tick
• Implement transducer T₃, which removes the clock tick and permutes the possible sends/receives between agents
• Implement the pruning of the arena to ensure only valid paths exist
