ahocorasick: Fast Multi-Pattern String Matching with the 'Aho-Corasick' Algorithm

Provide fast multi-pattern string matching for 'R' using the 'Aho-Corasick' algorithm, powered by the 'Rust' 'aho-corasick' crate. It builds reusable automatons for detecting matches, counting matches, locating character, extracting matched text, and replacing matches in character vectors. For more details on the 'Aho-Corasick' algorithm, please see Aho and Corasick (1975) <doi:10.1145/360825.360855>.
