Version 0.4.0

• Add xpluck() function.
  • xpluck() works like purrr::pluck(), but allows you to specify multiple indices at each step, e.g. xpluck(x, 1:2, c("a", "b")).
• Deprecate xmap_raw() and future_xmap_raw() functions.
  • purrr::map_raw() and other *_raw() functions are deprecated in purrr 1.0.0.
