Add more png benchmarks for alternative mimic libs

On a mid-range x86_64 laptop:

"libpng" (Debian's /usr/lib/x86_64-linux-gnu/libpng16.so) numbers are
used as a 1.00x baseline for the other libraries.

(†): libpng's "simplified API" doesn't provide a way to ignore the
checksum. We copy the "verify_checksum" numbers for a 1.00x baseline.
Some of the other libraries don't have the option to ignore or verify
the checksum, always doing only one or the other.
