Closes #7572 by adding a cache for compiled regexes of type `Arc<Mutex<LruCache<String, Regex>>>` to `EngineState` . The cache is limited to 100 entries (limit chosen arbitrarily) and evicts least-recently-used items first. This PR makes a noticeable difference when using regexes for `color_config`, e.g.: ```bash #first set string formatting in config.nu like: string: { if $in =~ '^#\w{6}$' { $in } else { 'white' } }` # then try displaying and exploring a table with many strings # this is instant after the PR, but takes hundreds of milliseconds before ['#ff0033', '#0025ee', '#0087aa', 'string', '#4101ff', '#ff0033', '#0025ee', '#0087aa', 'string', '#6103ff', '#ff0033', '#0025ee', '#0087aa', 'string', '#6103ff', '#ff0033', '#0025ee', '#0087aa', 'string', '#6103ff', '#ff0033', '#0025ee', '#0087aa', 'string', '#6103ff','#ff0033', '#0025ee', '#0087aa', 'string', '#6103ff','#ff0033', '#0025ee', '#0087aa', 'string', '#6103ff','#ff0033', '#0025ee', '#0087aa', 'string', '#6103ff','#ff0033', '#0025ee', '#0087aa', 'string', '#6103ff','#ff0033', '#0025ee', '#0087aa', 'string', '#6103ff'] ``` ## New dependency (`lru`) This uses [the popular `lru` crate](https://lib.rs/crates/lru). The new dependency adds 19.8KB to a Linux release build of Nushell. I think this is OK, especially since the crate can be useful elsewhere in Nu.
