2024-05-08 r/8095 refactor(nix-compat/nar/reader): reuse prev_name allocationedef1-1/+1
We reuse the prev_name allocation for Entry, instead of allocating and returning a separate Vec. We encode the `prev_name: None` case as an empty vector, since we don't allow empty names anyway, and the sorting is equivalent.

This is a tool for ingesting subsets of cache.nixos.org into its own flattened castore format. Currently, produced chunks are not preserved, and this purely serves as a way of measuring compression/deduplication ratios for various chunking and compression parameters.
