OBS Studio is a little bit behind with the FFmpeg Binaries, so the Zeranoe binaries will lead to the plugin being unable to load - which is not what we want. Instead just use the OBS Studio dependencies and offer a way to specify an already downloaded directory and also respect FFmpegPath if set.
Massively speeds up repeated builds by not relying on random undeterministic download speeds of the AppVeyor machines, in addition to reducing the stress on the remote end for each build done. Additionally the logging changes make it so that the errors and warnings are shown in the AppVeyor UI.
