Downloads the original record once (pinned to the imported snapshot) and caches it.

Any dataset here, as the library's Tabulated material (zeonexe48r/sultanova-2009).

# ... load zeonexe48r as above, then:
sim = ls.Simulation(
    particles=[ls.Particle(shape=ls.Sphere(radius_nm=50), material=zeonexe48r)],
    medium_index=1.0,
    wavelengths=ls.WavelengthRange(start_nm=437, stop_nm=1000, num=81),
)
res = ls.solve(sim)  # exact Mie for a sphere
print(res.q_ext)     # extinction efficiency at each wavelength

Same spec runs with DDA, FDTD, BEM or T-matrix: ls.compare(sim, ["mie", "dda"]).
