feat: store dir structure compatible with pnpm (#166)

Resolves #165

**Other changes:**
* A new crate named `pacquet-store-dir` has been created.
* The field `store-dir` in `Npmrc` has been changed from `PathBuf` to `StoreDir`.
* The function `write_sync` in `pacquet-cafs` has been replaced by 2 functions (8f98e73).
* The `pacquet-cafs` crate has been merged into `pacquet-store-dir` (db673ef).
* The `pacquet-tarball` crate now also writes index files (3b6e68a..8f98e73).
* The command `pacquet prune` now panics on `todo!()` for being incomplete (c8526d0).
