butcher 0.3.1

butcher 0.3.0

Added an axe_fitted() method to butcher the template slot for prepped recipes (@AshesITR, #207).
Added butcher methods for glm() (#212).
Removed axe_fitted() and axe_ctrl() for xgboost, because these methods caused problems for prediction (#218).
Moved usethis and fs to Suggests (#222).
Removed fastICA and NMF from Suggests. fastICA requires R >= 4.0.0 now, and NMF is often hard to install and was only used for one test (#201).
Preemptively fixed a test related to a recipes change in step_hyperbolic() (#220).
Transitioned unit tests to make use of modeldata::Sacramento rather than modeldata::okc in anticipation of okc’s deprecation in an upcoming release of modeldata (@simonpcouch, #219).

Added an axe_env() method to remove the terms environment for recipe steps. This covers most recipe steps, but certain steps still need more specific methods (@juliasilge, #193).

Ensure butcher is compatible with recipes 0.1.16, where a few steps have been renamed.
Fixed issue with survival 3.2-10, where butcher was using frailty terms incorrectly (#184).

Fixed an issue where axing a parsnip ‘model_fit’ would return the underlying model object rather than the altered ‘model_fit’.
Fixed a few test failures related to changes in parsnip (#157).

Examples for C50 objects were updated to reflect data files were now located in modeldata.

modeldata was added as a dependency since the data files required for testing axe methods on models objects instantiated for testing were moved into this library.
glmnet was removed as a dependency since the new version depends on 3.6.0 or greater. Keeping it would constrain butcher to that same requirement. All glmnet tests are run locally.
