zig core pending

[bkataru]

• maybe zig bindings for jax/xla?
• FFI to python & publish to pypi
• document new library, unique capabilities, git add, git commit, lint, prose lint, format, test (unit and integration), update docs, update CI, update usage instructions
• the idea is to provide a zig core which can be used directly with zig (obviously) and through python via python-zig bindings

we need to figure out how to use Zig as a build system to successfully build jax and/or xla

an alternative Rust core leveraging a diff geo engine using types as computation (diffable) has been added and published on crates.io as well
