Remove imports from gsl.all

I had troubles with importing `gsl` (on Windows) and tried to fix it by changing imports from `gsl.all` to more specific imports. Turns out the real problem was actually wrong `pkg-config` entry; but I thought these more specific imports might be helpful anyway and should (slightly) reduce the size of the built library.
