abstract npm tarball making to separate crate

[shevernitskiy]

It would be nice to have a cli tool or gh action to prepare identical tarballs that JSR provide. Many user continue to make releases to npm as well as JSR. If tarball making logic will be easy accessable, it will ease whole proccess.

This will be available soon.

Solving this will also fix #595. People can then add a mostly empty package.json file to their repository, add the jsr command line tool as a dev dependency, and use it to compile the package from a prepare script. That would integrate extremely well with existing workflows.

We are going to migrate our ecosystem to JSR, with some packages being ⭐⭐ Very Popular on /x. I am looking forward to this CLI!

@lucacasonato how soon is soon? Is somebody already working on this? Do you need help from the community? I'm eagerly waiting for this as it is the last thing that's blocking a bunch of migrations.

Update: @ry has confirmed on Discord that this is still a thing (despite the silence), and that it will be shipped with “probably the next batch of features.”
