Adds regex length range analysis

Adds a new feature to analyze regular expressions and determine the minimum and maximum possible lengths of strings that match the regex.

This is achieved by implementing a `LengthRangeNodeVisitor` that traverses the regex's AST and calculates the length range.

This information is useful for input validation and optimization.
