Adding new tokens

[SatyamSingh8306]

Summary

Adds support and verifying for various tokens in the lexer.py, including bitwise operators (BITWISE_AND, BITWISE_OR, BITWISE_XOR, BITWISE_NOT), assignment operators (ASSIGN_AND, ASSIGN_OR, ASSIGN_XOR, ASSIGN_MOD, ASSIGN_SHIFT_LEFT, ASSIGN_SHIFT_RIGHT), logical operators (LOGICAL_AND, LOGICAL_OR), and data types (DOUBLE, UNSIGNED_INT). These updates expand the lexers.py capabilities to identify and process these tokens accurately.
