Description:
------------
At present, we encounter 
"Warning: exif_read_data(somefilename.png): File not supported" 

With the July 2017 extension, PNG now has registered a standard way to express an EXIF block:
ftp://ftp.simplesystems.org/pub/png/documents/pngreg-1.5.0.html
http://ftp-osl.osuosl.org/pub/libpng/documents/pngext-1.5.0.html#C.eXIf 

Since this block had already been in prior use by the various graphics tools, I respectfully ask that it also be included in the PHP Exif library?
