-zlib-rs = ["any_zlib", "libz-rs-sys"]
+zlib-rs = ["any_impl", "dep:zlib-rs"]

zlib-rs doesn't enable any_zlib anymore, so APIs under any_zlib like Compress::new_gzip, Compress::set_dictionary became unexisting.

I assume this might be intended, but it is surprising change between 1.1.5 -> 1.1.7 because I can't pin the version as 1.1

What will be the migration guide in that case?
