4.73

svtplay: fix crash on some clips
removed —audio-role (all the interesting audio is in the —audio-language)
added —video-role. works like —audio-role. but with some improvement. for example alternate-sign role for teckenspråkstolkat. some downloaded videos in 4.71 and 4.72 might have gotten the wrong video because of this…
added -R for reversed download order with -A. thanks to @ml-1
