Add SD `web-dl` support

Fixes detection of things like `Project.Runway.All.Stars.S03E02.Bitten.By.The.Fashion.Bug.WEB-DL.x264-RKSTR`
`Cutthroat.Kitchen.S01E03.Tac-o.the.Town.WEB-DL.x264-JIVE`

  > This will pick up mSD's 480 web-dl encodes now. So people may want to add ignore_word for `480p` to stop those.
