store packages uncompressed in s3 (support a private unpkg)

[benjamine]

I'd like to download files inside a package, similarly to how unpkg.com does for the public npm registry. this would be trivial to implement if verdaccio had an option to store package contents uncompress in s3 (besides the .tgz file),

Describe the solution you'd like have a config option to ask verdaccio to also store package contents in s3 uncompressed in a subfolder. ideally only for specific package namespaces.

Describe alternatives you've considered this might be doable with an AWS lambda, subscribed to the creation of .tgz files, that at that time decompress and stores the files next to it.
