Use COBYQA instead of COBYLA with scipy >= 1.14 in scipy.optimize.minimize

[jorenham]

Since SciPy 1.14 the method='COBYQA', which is supposedly a better method than 'COBYLA'.

Be sure to check whether this actually leads to faster runtimes, and doesn't negatively impact the accuracy too much.

• lmo.diagnostic.error_sensitivity, see also Vectorize diagnostic.error_sensitivity with scipy.optimize.elementwise.find_minimum on scipy>=1.15 #363
