1. Make blake3 C library usable as meson subproject …

   The meson build system[1] support subprojects - a way to use another
   project in your build. The blake3 C library can be used like this, but
   meson requires that the subproject root directory has either
   `meson.build` (for meson projects) or `CMakeLists.txt` (meson can build
   cmake projects).
   
   Add `CMakeLists.txt` in the root directory with the project info,
   including the `c` subdirectory. With this you can add blake3 as
   subproject to a meson project.
   
   Example wrap file (using test release from my fork):
   
       % cat subprojects/blake3.wrap
       [wrap-file]
       directory = BLAKE3-1.4.1-cmake
       source_url = https://github.com/nirs/BLAKE3/archive/refs/tags/1.4.1-cmake.tar.gz
       source_filename = BLAKE3-1.4.1-cmake.tar.gz
       source_hash = 6c6f053ede700d76d12a7ced7bbd640e7a47f97122fe4cbe718aa9406251d043
   
   With this wrap file, you can use blake3 in your meson project[2] like this:
   
       % cat meson.build
       project('blake3-meson', 'c', default_options: ['buildtype=release'])
       cmake = import('cmake')
       blake3_subproj = cmake.subproject('blake3')
       blake3_dep = blake3_subproj.dependency('blake3')
       executable(example, ['example.c'], dependencies: blake3_dep)
