In tidymodels/stacks: Tidy Model Stacking

fit_members errors informatively with a bad model_stack arg

Code
  st_reg_1 %>% fit_members()
Condition
  Error in `fit_members()`:
  ! The supplied `model_stack` argument is a data stack rather than a model stack. Did you forget to first evaluate the ensemble's stacking coefficients with `blend_predictions()` (`?stacks::blend_predictions()`)?

Code
  "howdy" %>% fit_members()
Condition
  Error in `fit_members()`:
  ! Element model_stack needs to inherit from `model_stack`, but its class is `character`.

Code
  out <- st_reg_1__ %>% fit_members()
Condition
  Warning:
  The members in the supplied `model_stack` have already been fitted and need not be fitted again.

fit_members checks for required packages

Code
  error_needs_install(letters[1], rep(FALSE, 1))
Condition
  Error in `error_needs_install()`:
  ! The package a needs to be installed before fitting members.

Code
  error_needs_install(letters[1:2], rep(FALSE, 2))
Condition
  Error in `error_needs_install()`:
  ! The packages a and b need to be installed before fitting members.

Code
  error_needs_install(letters[1:3], rep(FALSE, 3))
Condition
  Error in `error_needs_install()`:
  ! The packages a, b, and c need to be installed before fitting members.

Code
  st_reg_1_ %>% fit_members()
Condition
  Error in `fit_members()`:
  ! The packages recipes, parsnip, and kernlab need to be installed before fitting members.
