pak 0.4.0

• pak has much improved and more informative error messages now.
  This work is not yet finished, so if you find an unclear error message,
  please open an issue. Thank you!

• The solver is now more robust for non-canonical input (e.g. DESCRIPTION
  files) (#423).

• Better installation output. Standard output and error are now
  collected together (r-lib/pkgdepends@0669f0f8c).

• The solver is now doing a better job when multiple versions of the
  same package are present in the same repository
  (r-lib/actions#559).

• pkg_name_check() now works again, it needed a fix after changes at
  https://crandb.r-pkg.org.

• Explicit package names in local and URL package sources, as in
  package=local::... or package=url::... are now parsed correctly in
  dependencies.

• pak is now more robust to Archs fields missing from the CRAN
  metadata for packages with compiled code
  (#448).

• url:: packages now always work correctly, even if the digest package is
  not installed (#433).

• pak is now more robust when installing packages from subdirectories
  of GitHub repositories (#431,
  @paleolimbot).

• Parameters ?reinstall, ?source and ?ignore now work correctly when
  specified in the package=?parameter format (#294).

• The ?ignore parameter works correctly now.

• Dependency resolution now does not fail if a package is not found.

• pak can now install url:: remotes from GitHub.

• pak now does not fail when the package of a .tar.gz GitHub
  snapshot is in a subdirectory, or in a subdirectory of a subdirectory.

• pak now errors early if it cannot deduce the name of the package
  from a Remotes or Config/Needs/* entry.

• Solver failures now include details in some cases where previously they
  did not.

• pak can now update packages in Docker containers where the
  old version was installed in the different Docker later
  (#251)

• Update R version -> Bioconductor version mapping. R 4.2.x now maps to
  Bioconductor 3.16.
