[parse] long file handling

[pi0]

Environment

Reproduction

https://stackblitz.com/edit/stackblitz-starters-rnsaetcx?file=index.mjs

Describe the bug

GitHub tarball paths for filenames are inconsistent. It seems it assumes we should inherit last dir name and prefix it to names.

I have to do little more research if there is some meta specific to this behavior we might be missing or it is just a convention to follow by default.

long paths should be handled from previous tar entries
