XtX_inv is provided

Code
  new_apd_hat_values(blueprint = hardhat::default_xy_blueprint())
Error <simpleError>
  argument "XtX_inv" is missing, with no default

new_apd_hat_values fails when blueprint is numeric

Code
  new_apd_hat_values(XtX_inv = 1, blueprint = 1)
Error <rlang_error>
  blueprint should be a blueprint, not a numeric.

apd_hat_values fails when matrix has more predictors than samples

Code
  apd_hat_values(bad_data)
Error <rlang_error>
  The number of columns must be less than the number of rows.

apd_hat_values fails when the matrix X^tX is singular

Code
  apd_hat_values(bad_data)
Error <rlang_error>
  Unable to compute the hat values of the matrix X of
  predictors because the matrix resulting from multiplying
  the transpose of X by X is singular.
