(devel/R-withr) Updated  2.4.3 to 2.5.0

# withr 2.5.0

* `defer()` and all `local_*()` functions now work when run inside of
  a `.Rmd`. The deferred expressions are executed when knitr exits.

* `defer()` and `local_` functions now work within `source()`.
  The deferred expressions are executed when `source()` exits.

* `with_()` and `local_()` gain a `get` argument. Supply a getter
  function to create `with` and `local` functions that are robust to
  early exits.

  When supplied, this restoration pattern is used:

  ```
  old <- get()
  on.exit(set(old))
  set(new)
  action()
  ```

  Instead of:

  ```
  old <- set(new)
  on.exit(set(old))
  action()
  ```

  This ensures proper restoration of the old state when an early exit
  occurs during `set()` (for instance when a deprecation warning is
  caught, see #191).

* These `with_` and `local_` functions are now robust to early exits (see next \ 
bullet):

  - `_locale()`
  - `_envvar()`
  - `_libpaths()`
  - `_options()`
  - `_par()`
  - `_path()`
  - `_seed()`

* `with_namespace()` and `local_namespace()` now pass `warn.conflicts`
  to `attach()` (@kyleam, #185).

* `local_rng_version()` and `local_seed()` no longer warn when
  restoring `sample.kind` to `"Rounding"` (#167).

* `with_seed()` now preserves the current values of `RNGkind()` (#167).

* `with_collate()` is no longer affected by the `LC_COLLATE`
  environment variable set to "C" (#179).

* Local evaluations in the `globalenv()` (as opposed to top-level
  ones) are now unwound in the same way as regular environments.

* `local_tempfile()` gains a lines argument so, if desired, you can pre-fill
  the temporary file with some data.
