devel/R-pkgdepends: import R-pkgdepends-0.8.0

Find recursive dependencies of 'R' packages from various sources.
Solve the dependencies to obtain a consistent set of packages to
install. Download packages, and install them. It supports packages on
'CRAN', 'Bioconductor' and other 'CRAN-like' repositories, 'GitHub',
package 'URLs', and local package trees and files. It caches metadata
and package files via the 'pkgcache' package, and performs all 'HTTP'
requests, downloads, builds and installations in parallel.
'pkgdepends' is the workhorse of the 'pak' package.
