Mac: buffer more output frames to avoid audio input lag issue

goal is to eradicate these warning messages which indicates the buffer has been filled and
audio will be restarted:
coreaudio_input_capture_63f7ec05-cafb-49af-aea8-c8240e1246be audio is lagging (over by 51.92 ms) at max audio buffering. Restarting source audio.
Source mac_screen_capture audio is lagging (over by 5.66 ms) at max audio buffering. Restarting source audio.
