Silence console output

[peastman]

I am using the ASE interface like this:

atoms = ase.Atoms(positions=pos, numbers=numbers, charges=charges)
atoms.calc = XTB(method="GFN-FF")
ase.optimize.LBFGS(atoms, logfile=os.devnull).run(0.001, 20)

Despite directing the log to devnull, the optimizer still prints about a hundred lines of output every time I do this:

          ==================== Thresholds ====================
          CN  :   150.00000
          rep :   500.00000
          disp:  2500.00000
          HB1 :   250.00000
          HB2 :   450.00000

and so on. Is there some way I can silence the output? Here are the relevant package versions (installed with conda).
