Additional Fast Forward and Rewind Options

15/30 second forward or back on videos. I'm not sure what the actual features are called, but having the ability to do a quick rewind/fast forward option while watching videos would be great! Edit: There are -5/+5 second fast forward and rewind options available in the player settings, https://app.searchie.io/settings/player-settings, but this feature request would add additional +/-15, +/-30 second, or other options.
