No longer use LUT for 32bit input 
That means you’ll finally get full 32bit precision, not just 8bit.
This comes at a cost (~20% lower FPS), but it’s a lot more accurate,
and there’s potentially room for optimization in the future because we
actually do math now instead of just hacky lookups in a 256-element
vector.

Remove unneeded test import 
Now this builds on stable again. I’ll put future benchmarks under
benches/ to be sure.

Optimize LUT generation 
Directly calling f32::mul_add is actually more accurate and faster here
because rustc seems to be unable to rearrange the original instructions
in a way that can utilize `fma`.
When directly comparing the two implementations, mul_add was about 10%
faster on my machine (Ryzen 1700 with native target in rustflags).

Add error message for invalid float input 
A few people encountered these. Looks like a few other filters don’t
clip their limited range output properly.
