This change updates the mac-virtualcam implementation to conditionally enable conversion of the output video format. Previously, the output video was always converted into UYVY. However, this conversion exhibits high CPU usage, as reported in: https://github.com/johnboiles/obs-mac-virtualcam/issues/102 Therefore, we disable conversion when the selected output format (e.g., NV12) is natively supported by CoreVideo's pixel buffers.
