bb_optimize vs tune

[sumny]

Some minor inconsistencies I stumbled across:

In tune (mlr3tuning), ... is passed to the constructor of the tuner
In bb_optimize ... is either assumed to pass constants (bb_optimize.function) or it is simply ignored (bb_optimize.Objective). Both ways do not allow for initializing the optimizer with e.g. different hyperparameters on the fly

You can use bb_optimize(method = opt("random_search", batch_size = 10) to set hyperparameters. Yes it is an inconsistencies between these functions but we found it more useful to pass constants in ... for bb_optimize().
