## Description

CHTCollectionViewWaterfallLayout is a custom layout for iOS collection views designed to organize items of varying heights into a masonry-style grid. It enables the display of dynamic content in multiple columns to optimize screen space and visual flow.

The layout allows for specific configuration of column counts and item population directions, including left-to-right, right-to-left, and shortest-column-first rendering patterns. This approach minimizes vertical gaps by placing items into the column with the lowest current height.

The system also manages section-level accessories, integrating headers and footers with custom heights and spacing. It supports unique column configurations and spacing rules mapped to different sections of the layout.
