Description of the change
Adds an immutable strings library to benefit future systems.
fixes https://linear.app/art-blocks/issue/PRO-1104/immutable-strings-array-solidity-library
This adds a library that efficiently uses contract bytecode to efficiently store immutable arrays of strings. This massively reduces gas costs when storing and loading string arrays.
Assembly is thoroughly commented and simplified for readability.
Tests
Tests are added for coverage of the new functionality, as well as edge cases.
