Log Message:
(lang/R-cpp11) Updated 0.4.3 to 0.4.7

# cpp11 0.4.7

* Internal changes requested by CRAN to fix invalid format string tokens
  (@paleolimbot, #345).

# cpp11 0.4.6

* R >=3.5.0 is now required to use cpp11. This is in line with (and even goes
  beyond) the tidyverse standard of supporting the previous 5 minor releases of
  R. It also ensures that `R_UnwindProtect()` is available to avoid C++ memory
  leaks (#332).

* `cpp11::preserved.release_all()` has been removed. This was intended to
  support expert developers on R <3.5.0 when cpp11 used a global protection
  list. Since cpp11 no longer uses a global protection list and requires R
  >=3.5.0, it is no longer needed. As far as we can tell, no package was
  actively using this (#332).

* cpp11 now creates one protection list per compilation unit, rather than one
  global protection list shared across compilation units and across packages.
  This greatly reduces the complexity of managing the protection list state and
  should make it easier to make changes to the protection list structure in the
  future without breaking packages compiled with older versions of cpp11 (#330).

* Nested calls to `cpp11::unwind_protect()` are no longer supported or
  encouraged. Previously, this was something that could be done for performance
  improvements, but ultimately this feature has proven to cause more problems
  than it is worth and is very hard to use safely. For more information, see the
  new `vignette("FAQ")` section titled "Should I call \ 
`cpp11::unwind_protect()`
  manually?" (#327).

* The features and bug fixes from cpp11 0.4.4 have been added back in.

# cpp11 0.4.5

* On 2023-07-20, cpp11 was temporarily rolled back to 0.4.3 manually by CRAN due
  to a bug in 0.4.4 which we could not immediately fix due to the cpp11
  maintainer being on vacation.

# cpp11 0.4.4

* Davis Vaughan is now the maintainer.

* `as_doubles()` and `as_integers()` now propagate missing values correctly
   (#265, #319).

* Fixed a performance issue related to nested `unwind_protect()` calls (#298).

* Minor performance improvements to the cpp11 protect code. (@kevinushey)

* `cpp_register()` gains an argument `extension=` governing the file extension of
  the `src/cpp11` file. By default it's `.cpp`, but `.cc` is now supported
  as well (#292, @MichaelChirico)
