Prerelease: no

Release notes: This release adds support for I8 vectors as well as binary (BIN) and scalar 8-bit (Q8) quantizers. For f32 vectors, the available quantizers are now NOQUANT, BIN, and Q8. For u8 and i8 vectors, XNOQUANT_U8, XNOQUANT_I8, XBIN_U8, and XBIN_I8 are available.

The version is now 2.0.0 to account for the FFI changes.

Note, quantization support is not yet persisted to disk, so this release should be used for in-memory workloads only. Persistence will follow shortly.
