add_resample_weights() validates inputs correctly

Code
  add_resample_weights("not_an_rset", c(0.5, 0.3, 0.2))
Condition
  Error in `add_resample_weights()`:
  ! `rset` must be an rset object.

Code
  add_resample_weights(folds, c("a", "b", "c"))
Condition
  Error in `.validate_resample_weights()`:
  ! `weights` must be numeric.

Code
  add_resample_weights(folds, c(0.5, 0.3))
Condition
  Error in `.validate_resample_weights()`:
  ! Length of `weights` (2) must equal number of resamples (3).

Code
  add_resample_weights(folds, c(-0.1, 0.5, 0.6))
Condition
  Error in `.validate_resample_weights()`:
  ! `weights` must be non-negative.

Code
  add_resample_weights(folds, c(0, 0, 0))
Condition
  Error in `.validate_resample_weights()`:
  ! At least one weight must be positive.

extract_resample_weights() validates input types

Code
  extract_resample_weights("not_valid_input")
Condition
  Error in `extract_resample_weights()`:
  ! `x` must be an rset or tune_results object.

Code
  extract_resample_weights(data.frame(x = 1:3))
Condition
  Error in `extract_resample_weights()`:
  ! `x` must be an rset or tune_results object.
