Update the lexing implementation to defer to the regex library, which will pass back the pointer from to resume lexing, and update the emission to call the new `Regex(_regexString:version:)` overload, that will accept the regex string with delimiters. Because this uses the library's lexing implementation, the delimiters are now `'/.../'` and `'|...|'` instead of plain `'...'`.
