[Feature request]: implement "subsampling" for higher resolution outputs from inswapper128

[fourletterkey]

Feature description

hillobar's rope pearl can output higher resolution swaps using the 128 model without the use of face restoration. it does this using a neat trick. this would be nice to see implemented as a functionality in reactor since from my testing. for whatever reason, reactor still beats rope for likeness.
maybe this trick could be ported over to reactor to get the best of both worlds? (rope's resolution and reactor's likeness)
