* Add a string-specific search algorithm This adds a Boyer-Moore substring search algorithm, and updates the `firstRange(of:)` and `ranges(of:)` methods to use that when both pieces of the search are strings/substrings. * Substring search: iterative rather than recursive For large strings, a recursive search can run out of stack space. This eliminates the issue by looping within the `nextRange` function. * Dispatch string splitting to new searcher * Remove generic on SubstringSearcher * Remove unnecessary inlining annotations * Update string algorithms tests * Verify string/substring dispatch in algorithms * Add tests for string.replacing maxReplacements * Add fallback to naive search for small patterns * Improve some comments/formatting in the string search
