rife-v2.3 Interpolation factors beyond 2x

[NenelFX]

hello, would it be possible to add support for 4x and x8 to the rife-v2.3 version equal to rife-v4
because I use rife-v2.3 to interpolate animes and the one I use the most
if possible please add support to this version
because my pc has no way to use the cuda version of the rife

in my case rife-v2.3 is the best version
