Add a new SymbolTable module for interned string identifiers. The module implements a bidirectional mapping between strings and Symbol IDs using a HashMap. Key functionality includes: - intern(): Add a string to the table and return its Symbol ID - get(): Look up a string by Symbol ID - resolve(): Get the original string for a Symbol ID - intern_pair() and intern_coords(): Helper functions for structured data interning The implementation includes unit tests to verify correct behavior.
