v0.12.1 - The Bleeding Lance

New features

• A KL divergence method to compare two distributions.
• Two methods that reduce the number of states in a BSDistribution to help comparing distributions.
• A qloq ansatz in the catalog to help building ansatz with qudit encoding.
  See https://perceval.quandela.net/docs/v0.12/notebooks/QLOQ_QUBO_tutorial.html

Improvements

• The catalog now includes usual 1-qubit gates.
• The CircuitOptimizer can now ignore columns of the unitary given a list of modes that won't receive input photons.
• Perceval's Qiskit bridge is now using Qiskit 1.3.1
• Feed-forward simulation is now faster when using heralds.
• Noisy input state generation is now faster and is now only dependant on the number of photons.

Bug fixes

• LC and TD simulation now succeed if there are empty modes at the end of the Processor.
• Fixed performance computation when using LC and TD.
• Fixed potentially wrong results when using several layers of feed-forward.
• The Sampler iterator no longer need heralded modes to be defined in the input state.
• Fixed a crash when trying to display a circuit having empty sub-circuits.
