v2.1: `PinnedVec`, `RoundRobinVec`, and `SpinMutex` for Rust 🦀

This PR introduces a significant amount of functionality for Rust and provides portability improvements for C++. Regarding the former, the compilation of different sections is now better guarded, and some of the Assembly instructions are encoded manually to increase compatibility.

On the Rust side, many new classes were added. SpinMutex replaces Mutex, similar to spin_mutex in our C++ layer. PinnedVec provides Vec-like functionality, but is built around PinnedAllocator to attach to a certain NUMA node. It's not just a Vec alias with a custom allocator, as our primary allocate_at_least API differs from Rust's Nightly standard library. More interestingly, RoundRobinVec is a NUMA-distributed container for vast arrays of data, with most operations expecting an additional threads pool argument to distribute the work across the entire machine.

Check out scripts/search.rs for NUMA-aware Vector Search examples leveraging SimSIMD.
