Xattr & cleaner code

• Added xattr extraction support.
• Added some flags to unsquashfs
  • --force
    • Currently this just deletes the extraction location before extracting.
  • -dx - Don't apply xattrs
  • -dp - Don't apply file permissions.
• We are now using Zig packaged version of zlib-ng, lz4, and zstd.
  • This should provide a more consistent build experience and allows for static linking.
• Lookup tables are now separated out into a separate struct, with the value being null by default in an Archive.
  • This is to fix some race conditions when extracting.
• Replaced -Dvalgrind build flag with -Ddebug that enables several build options that help with debugging.
• Replaced -Duse_c_libs build flag with -Duse_zig_decomp, making using C libraries the default.
• Did some cleanup so that the code should be more readable & logical.

Full Changelog: v0.0.5...v0.0.6

v0.0.5

• Add more explicit Allocator arguments to many functions. Previously the library would largely use the Archive's allocator.
• Fixed a couple bugs relating to extraction
  • Fixed bug from setting a file's modified time
  • Fixed bug from multi-threading WaitGroup
• Made ExtractionOptions public.
• Moved setting thread count to ExtractionOptions instead of when creating an Archive.
  • To facilitate this, Default is now a function that returns an error union (VerboseDefault now also returns an error union)
  • There's now a SingleThreadedDefault option.
• Removed initAdvanced in favor of just init.
