6d49d7b8f9 Implement zopfli compression, available as a CLI flag (-Z) 
Improves compression by about 10% over DEFLATE, but takes a very long
time at the moment, so it is off by default.

7460ffac73 Fix for passing in filenames that contain commas 
The versions of clap supported by oxipng default to allowing commas to be used as a delimiter for passing a series of values in a single physical command line argument, when parsing for a parameter that accepts multiple values. This prevents oxipng from accepting filenames containing commas (it splits them into segments separated by commas and treats each one as a separate path to a file to process, generally not finding any); this patch fixes this by disabling the delimiter behavior for the 'files' argument.

f3b8665278 Use miniz for compression strategies 0 and 1

magnitude better than miniz
