dials 1.1.0

New parameters

• Added learning rate scheduler parameters rate_decay(), rate_initial(),
  rate_largest(), rate_reduction(), rate_schedule(), rate_step_size(),
  and rate_steps() for the new brulee functions (#253).

• Added num_clusters() parameter for tidyclust models (#259).

• Added num_leaves() parameter for lightbgm models (@joeycouse, #256).

Other changes

• The default argument to the constructors new_quant_param() and
  new_qual_param() is deprecated. value_seq() now uses the same logic to
  generate a sequence of parameter values regardless of how long that sequence
  is (#153, #229).

• prior_terminal_node_expo() for Bayesian adaptive regression trees (BART) now
  defaults to a range greater than 1 to limit explosive tree growth (#251).

• The label for spline_degree() was improved.
