Bump pyzx from 0.10.2 to 0.10.3

[dependabot]

Bumps pyzx from 0.10.2 to 0.10.3.

Release notes

Sourced from pyzx's releases.

v0.10.3

Added

• The circuit generation functions in pyzx.generate now accept an additional optional argument, sigma, allowing a CNOT spread based on a Gaussian distribution rather than a uniform distribution for control over how localised the CNOTs should be. (by @​mjsutcliffe99).

Deprecated

• Deprecated pyzx.simulate.py as it is starting to get bloated with all the new decompositions and strategies that have been added in recent years. All the functions in this file should still work (with deprecation warnings) but are rerouted to their new homes under the pyzx.simulation folder. (by @​mjsutcliffe99).

Changed

• Refactored the simulation API to make it more formulaic and extensible. Individual decompositions are no longer included as distinct functions inside pyzx.simulate.py but now are provided their own individual files under pyzx.simulation.decompositions and share a common caller function. For example, pyzx.simulate.apply_cat3(g,v) is instead now pyzx.simulation.apply_decomp(Decomp.CAT_3,g,v), etc. (by @​mjsutcliffe99).
• Likewise, decomposition strategies are separated into individual files under pyzx.simulation.strategies and called similarly through e.g. zx.simulation.full_decompose(Strategy.BSS,g). (by @​mjsutcliffe99).

Added

• pyzx.simplify.drop_orphan_reset_discards: opt-in cleanup pass that removes the disconnected boundary -- Z(0) -- X(_rN) components left behind by Circuit.to_graph(elide_initial_resets=False) on circuits with leading resets, matching the elided graph with |0⟩ applied to those inputs (by @​dlyongemallo).

Fixed

• Multigraph handling of parallel mixed simple/Hadamard edges in tensor contraction, several rewrite rules, and PauliWeb (by @​dlyongemallo).
• Reset gate representation changed from ground-based to symbolic boolean paradigm, avoiding paradigm-mixing issues that destroyed measurement phases during simplification of circuits with mid-circuit resets. As a side effect, graph_to_circuit now recovers conditional X-type rotations (NOT, XPhase, SX), since X-type vertices on the qubit wire are unambiguous now that measurement outcomes are represented as leaves. Circuit.to_graph gains an opt-in elide_initial_resets flag (default False) that skips the discard chain for a Reset on an unmodified input wire, useful for circuits with OpenQASM-style implicit |0⟩ inputs. Each _rN reset variable is allocated to the lowest name not already in the graph's variable registry to avoid aliasing user-supplied phases, and graph_to_circuit excludes vertices on classical-bit wires (e.g. the Z/X pair from DiscardBit) so hybrid graphs round-trip without extra phantom qubits (by @​dlyongemallo).
