Support index.add(x, y) alias which is the same as index.add(x, y, x, y) — a convenient way to add points to the index.

Accept byteOffset as an optional argument in Flatbush.from (for recreating an index from a part of a buffer). #55 by @kylebarron

• Fix a bug where index.neighbors(x, y) without other arguments would freeze in an infinite loop. #50
• Improve performance of distance-bounded neighbors queries. ce745eeafd9b1be3c63cc9fb71fa5387550ad464
• Introduce first-class TypeScript typings in place of third-party ones from DefinitelyTyped. #47

• Add SharedArrayBuffer support by @jdesboeufs in https://github.com/mourner/flatbush/pull/46.
• Minor performance optimizations.
• Switch to native Node test runner for development (requiring Node v18+ to contribute).

• ⚠️ Drop CommonJS entry point in favor of a ESM-only Node entry point.
• Drop bundle transpiling and support for IE11 (users can still do that on their end).
• UMD bundle for browsers is still available.

• Slightly improve kNN search performance. https://github.com/mourner/flatbush/commit/6903d4b2c430628dbaaac19b11a1d12da97b285e
• Fix an error when data extend had zero width or height. https://github.com/mourner/flatbush/commit/306fecfbef8485b3a0740ed591f02cbb06126ee8 #34

• Improve indexing performance by 5–8%. #29
• Add a fast path for the case of the number of items being less than nodeSize. #28

Improve kNN performance by ~10-15%.

index.add(x0, y0, x1, y1) now returns the item's index.

Slightly faster kNN search.
