Typing stubs for antlr4-python3-runtime

This package provides static type checking stubs for the `antlr4-python3-runtime` library, enabling type checkers like MyPy and Pyright to analyze code that uses ANTLR 4's Python runtime. It is part of the `typeshed` project and aims to provide accurate annotations for `antlr4-python3-runtime==4.13.*`. Releases are frequent, often incorporating a date suffix, reflecting updates within the `typeshed` project and alignment with the underlying runtime.
