Fix Rust PNG benchmark

The Rust PNG benchmark no longer compiles. This is similar to the issue
that was fixed in pull request #68 for the Rust GIF benchmark. A new
version of the png crate was published that broke clean builds. I've
pinned the version to 0.17, which is the newest, and changed the code to
use the new API.

NOTE: Parts of the png crate documentation hasn't been updated to
correctly list the new transformation defaults. The documentation for
the `normalize_to_color8` method does say that the defaults changed from
version 0.16 to 0.17.
