Challenging a binary neutron star merger interpretation of GW230529 - Initial data

The initial data for the binary configurations simulated in the paper "Challenging a binary neutron star merger interpretation of GW230529", arXiv:2508.08750. The initial data is created using FUKAv2 solvers and has the eccentricity reduced below 1e-3.
