Subject: Reformatted Lua LPeg lexers and added new convenience functions and
 pattern. `lexer.range()` replaces `lexer.delimited_range()` and
 `lexer.nested_pair()`. `lexer.to_eol()` replaces `patt * lexer.nonnewline^0`
 constructs. `lexer.number` replaces `lexer.float + lexer.integer`. Also added
 unit tests for lexer functions.
