Fix: Open TOML files in binary mode as required by tomllib

Fixed two instances where TOML files were opened in text mode instead of binary mode:
- Line 650: process_pyproject() method
- Line 716: process_pylock() method

The tomllib parser requires files to be opened in binary mode ('rb').
This fixes the TypeError when processing pyproject.toml and poetry.lock files.
