BMD API starting with 12.0 support 64 channels so enable it when using eligible SDK. UG ships currently 11.6 so it won't be enabled by default but user can ship own version. + replaced unneeded checks in display_decklink_reconfigure_audio with assert (not needed, this should not happen because the format is negotiated with `get_property(AUDIO_FORMAT)`` first)
