 - `StringExtractor.extractStrings` is linear in the data's size: it gathered each run a `Character` at a time and measured the string (`count`, linear) before every byte, so a run cost up to `maxLength` times its length. Runs are now gathered as bytes; the results are unchanged (checked against the previous implementation on random data).
