This adds an incremental reader to the png type. The reader uses
png::Reader::next_row
to try to decode the png one row at a time.This is a small breaking api change as
PNGDecoder::Reader
now becomesPNGReader
.There should probably be some new tests to check the reader with different buffers ect... but I am not entirely sure where they should go?
