Swift PNG 4.3 released

hi all, SwiftPNG 4.3.0 has been released!

This release is almost entirely focused on documentation, as much of the library’s existing docs had rotted due to evolution of tooling. We have rewritten the package’s examples and tutorials and repaired scores of broken doccomments, and the package’s documentation is now available on swiftinit.org.

for the adventurous, the 4.3.0 release also comes with a highly experimental pure-Swift gzip implementation which is available under the LZ77 module.
