pkgdepends 0.4.0

• pkgdepends 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) (r-lib/pak#423).

• Better installation output. Standard output and error are now
  collected together (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.

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

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

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

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