Use fixed array for lut generation 
The old version that was generated at runtime didn’t actually contain
1.0 as a value, so getting full white output for int input was impossible.

Update release build script 
Default binaries are now compiled for haswell or higher
because using FMA instructions results in a noticeable performance gain.

@ -45,15 +45,25 @@ No idea what the minimum version is,
Binaries for Windows and Linux are in the release tab.
## FAQ
**What’s the no-fma dll? Which one do I need?**
There are two Windows builds of the plugin, one for CPUs that support
[FMA instructions](https://en.wikipedia.org/wiki/FMA_instruction_set) and one for those that don’t.
If your CPU is a Haswell (for Intel) or Piledriver (for AMD) or newer,
you can use the regular version (which is about 20% faster).
Otherwise, grab no-fma.
The Linux build uses fma instructions.
I trust that if you’re a Linux user on older hardware,
you know how to compile your own binaries.
**Why do I have to call std.PlaneStats() manually?**
~~Because I didn’t want to reimplement it. `kagefunc.adaptive_grain(clip, show_mask=True)` does that for you and then just returns the mask.~~
Because I was too dumb to realize [this](http://www.vapoursynth.com/doc/api/vapoursynth.h.html#invoke) exists.
I’ll fix that at some point.
I’ll fix that at some point.™
**Why doesn’t this also add grain?**
I was going to do that originally,
but it just goes back to the same point
about not wanting to reimplement
something that already exists.
but I didn’t want to reimplement grain
when we already have a working grain filter.
