Cqt 455 implement analyzer pass in open squirrel

[SoufiTNO]

Adds a new ''Analyzer'' pass type and the first concrete implementation, "'CircuitAnalyzer'', which computes structural metrics describing a quantum circuit. Metrics are organized into four categories :

• Size: number of qubits, gates, two-qubit gates, two-qubit gate percentage, depth
• Interaction graph (IG): average shortest path, std of adjacency, diameter, central dominance, average degree, number of maximal cliques, clustering coefficient
• Gate dependency graph (GDG): critical path length, path length mean/std, fraction of gates on critical path
• Density: density score, idling score
