Before this change, cf_OpenLibrary() was inconsistent. Sometimes, it would refer to the size of a HOG2 id using the literal 4. Other times it would refer to the size of a HOG2 id using strlen(HOG_TAG_STR). There was a good reason for this. Some compilers allow you to do this: char id[strlen(HOG_TAG_STR)]; Other compilers throw an error if you try to do that [1]. This commit makes cf_OpenLibrary() more consistent. It makes it so that cf_OpenLibrary() always uses the same constant expression when referring to HOG_TAG_STR’s length. [1]: <https://devblogs.microsoft.com/oldnewthing/20221114-00/?p=107393>
