io fails at the moment

I don't like the way that I'm doing it now, but I don't like the old way
more. With a static library, I no longer need to worry about installing
the package while running a simulation, etc.
Also, now I have full control over the arguments.

unlikely this would be a problem for most scenarios, but I might as well
use the correct values.

it's probably better than removing the whole file...

I think it helps...

FFTW says inplace is faster. I'm not so sure...

stupid multifractality

also, fix max_estimate value in call to vorticity moments

first of all, moments were completely broken because fields weren't
prepared properly.
secondly, normalization is not actually required.
