Test desirability functions A des func for finding large gradient

1	des_func_grad_norm2_mean(mod, XX, return_se = F)

`mod`	GauPro model
`XX`	Points to evaluate at
`return_se`	whether the se prediction should be returned along with the des, all will be returned in data.frame, this will save time if calculating the werror function since it is faster to predict both at once instead of separately
