Include pvporcupine resource files in PyInstaller build

PyInstaller wasn't bundling pvporcupine's resource files (keyword_files
and lib directories), causing a FileNotFoundError at runtime when
pvporcupine tried to access its resources directory.

Changes:
- Added code to detect and include pvporcupine resources and lib folders
- Falls back gracefully if pvporcupine is not installed
- Resources are bundled even though we don't use wake word features
  (pvporcupine initializes and checks for these on import)

This fixes the runtime error:
FileNotFoundError: [WinError 3] The system cannot find the path
specified: '...\pvporcupine\resources/keyword_files\windows'
