CRC call

[bhalonen]

Would this be a good package to implement the crc calls to zlib?

This package does not provide a function to calculate CRC32, but it's almost trivial to implement that using ccall and CodecZlib.libz.

I had a similar need and found the solution in Libz.jl. On the other hand, although these days I mostly write C code, I tend to disagree with the use of ccall. I don't think the community wants to see Julia become the new Numba.
