Update documentation and specifications of some of the zlib functions
The functions zlib:deflateSetDictionary/2 and zlib:inflateSetDictionary/2 accept iodata() as Dictionary. The functions zlib:crc32/2,3, zlib:adler32/2,3, zlib:compress/1, zlib:uncompress/1, zlib:zip/1, and zlib:unzip/1 accept iodata() as data.
