2.0.0

Performance & Refactoring

BREAKING CHANGE (Internal Access): Refactored the internal storage of Array2d

Benefit: This change significantly improves read/write performance and iteration speed by leveraging memory cache locality, as confirmed by benchmarks (up to 1.39x faster for random lookups).

Implementation: Now uses Column-Major indexing (k = x * height + y) to map 2D coordinates to the 1D index.

Fixes & API Consistency

Assignment Operator Fix: The indexed assignment operator (array[x][y] = value) is no longer supported for modifying elements in the 1D-backed structure.

The operator [] method now returns a copy (List

Action Required: Users must use the dedicated methods for writing and reading:

Set Value: Use array.setValue(x, y, value)

Get Value: Use array.getValue(x, y)
