fix: Reimplement stopHeartbeats function to fix MSVC builds

The stopHeartbeats function was removed in a previous commit, which caused MSVC builds to break. This commit re-adds the function to fix the build. The function will need to be reimplemented with the current codebase, as of right now this does nothing.
