Adding a collection of packages purely from tarballs

[Chardrazle]

If all required packages are available as local tarballs, should pnpm be able to resolve the dependencies?

Example:

# Acquire tarballs; note: using npm because AFAICT pnpm does not have an equivalent.
npm pack  punycode@2.1.0  uri-js@4.4.1

# Add packages
pnpm add  --offline ./punycode-2.1.0.tgz  ./uri-js-4.4.1.tgz
 ERR_PNPM_NO_OFFLINE_META  Failed to resolve punycode@>=2.1.0 <3.0.0-0 in package mirror <...>/metadata-v1.3/registry.npmjs.org/punycode.json

It shouldn't need the metadata, the package is right there.
