Planning to unretire rust-zopfli and rust-oxipng

[Ben Beasley]

As required by the Package Retirement Process[1], this email announces 
that I plan to unretire the rust-zopfli and rust-oxipng packages. Both 
were retired because they were “no longer needed,” but I would like to 
package the oxipng command-line tool, which is similar to the existing 
optipng tool.

I have already prepared PR’s that revert the unretirement commits and 
update each package to the latest version[2][3], and the packages are 
ready for re-review[4][5].
