added support for tumblr

- support for tumblr is back! (i tried all types of links in clear sight and everything seems to work, lmk if something doesn't)
- increased stream lifespan up to 1 hour
- made youtube audios download without additional conversion, speed should be a bit better but not by much cause youtube limits the audio download speed :(
