Marked osn_context as const in noise and extrapolate functions #12

Hi,

To my understanding, the noise & extrapolate functions should not (and actually, do not) modify the provided "osn_context" pointer. I think it should be marked as const (in these cases) in order to make room for optimisations (especially when calling from C++ code in my case).

Best regards!
