Replaced multiple file writes with a single string template write. The raw content is first grouped into 8 byte chunks, followed by another regex replace which wraps them in `std::byte`. Tested the output with `diff -w` and they're the same - only whitespace differences because slightly different source formatting. Tested the performance with: > time cmake -DRAW_SOURCE_PATH=src/bench/data/block413567.raw -DHEADER_PATH=build/after/block413567.raw.h -DRAW_NAMESPACE=benchmark::data -P cmake/script/GenerateHeaderFromRaw.cmake Before: > 15.41s user 23.06s system 97% cpu 39.593 total After: > 0.77s user 0.06s system 97% cpu 0.849 total
