HumanDynamo 3fe5ebb8ca PNG file format parser.
- Refactoring code: main loop to parse PNG chunk contents go to pngimage class. pngchunk only play with chunk contents
- Implement PNG writting mode : all metadata are supported: 
 * UTF8 comment as "Description" iTXt chunk (compressed)
 * XMP data as iTXt chunk (uncompressed as XMP spec instruction)
 * IPTC data as zTXt chunk (compressed and encoded as ImageMagick method)
 * EXIF data as zTXt chunk (compressed and encoded as ImageMagick method)
 
Note: writting mode resample metadata chunk to follow list given behind. There are several ways where other programs writte metadata in other place.
For ex : digiKam 0.9.x or ImageMagick 5.x writte Exif and Iptc to an tEXt chunk (uncompressed)
         ImageMagick 5.x writte Xmp to an uncompressed tEXt chunk
         ImageMagick 6.x writte Xmp to a compressed zTXt chunk.
