Add support for NLS stretch type feature

With apple announcing the support for projector aspect ratios I was wanting to make the request if we could get a NLS (Non linear Stretch) feature built into infuse for users who use it in a home theater like myself. Basically my idea is that for content not in the 2:35 or 2:39 aspect ratio it would apply that stretch to it so it could take up the full screen kind of like what the MadVR envy does with there NLS+. Hopefully I could get some feedback on this because I think it would be awesome to have infuse just automatically apply the filter on video titles that aren’t the same aspect ratio. Thanks

Edit* I’ve tried with this guys shader before on mpv player on windows and it does a pretty great job at it, NLS#
