Initial version

Description:
——————–
LibItemSets is a library for getting information about item sets.

Why use this library?

What’s the difference between LibItemSets and LibSets?

Console availability: LibItemSets is available for both PC and console, and LibSets is not.
Efficiency and performance: Even if LibSets were made available for console, its memory and performance footprint and would not be suitable for console’s limitations. LibItemSets was designed with performance and efficiency as the top priority. This means that it is missing some features found in LibSets, as it focuses on the functionality that most addons actually use. LibItemSets also uses on-demand initialization instead of unconditional initialization, meaning that it has virtually zero footprint until some addon actually tries to use it for the first time. And even after initializing, its memory footprint is still less than 1MB.

LibItemSets also has a venerable lineage: it was formerly the internal core data of Item Set Browser before it was spun out into a library so that other addons can make use of Item Set Browser’s data. As such, the data in LibItemSets has been maintained since 2016.
