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.
