sugar for trafos and composition of trafos

Do we still want that? Since we can now do this ```r search_space = ps( minsplit = p_dbl(lower = 1, upper = 10, , trafo = round) ) generate_design_grid(search_space, 3)$transpose()...

run unit test for tuning with deps in defaults

We do not check this anymore by default. This can be activated with `check_values = TRUE`. In this case the dependency must be set. Unit tests in #440.

Tuning SMOTE's K with a trafo fails: 'warning("k should be less than sample size!")'

This should be possible now with callbacks.

noisy / aggregation problem: how do we handle the fact that some tuners might evalutae some configs multiple times?

irace shows how to run the same configuration on different resamplings. The tuner adds a grouping variable to the archive and implements it's own `.assign_result` function.

Avoid duplicated results in tuning instance?

We decided that the tuner should handle this.
