fix: update antlr4 CMAKE_POLICY from OLD to NEW for CMake 3.31+ compatibility (#145) 

CMake 3.31+ has removed support for the OLD behavior of policies
CMP0042, CMP0045, CMP0054, and CMP0059. This causes a hard
configuration error when building from source with newer CMake versions.

Changing these to NEW resolves the build failure. The NEW behavior has
been the default since CMake 3.0/3.3 and does not affect functionality.

Fixes #144
