This commit renames ogg to m_OggStreamPtr for clarity and consistency with naming conventions. Additionally, it moves the m_Format and m_Frequency fields to the private section to ensure proper encapsulation. Local variables like pcmout have been renamed to PCMOut to match style conventions, and all member fields now follow a consistent m_ prefix style, placed at the end of the class definition for clarity. These changes help improve code readability, enforce privacy, and align with the rest of the codebase's naming standards.
