Add eXIf support to push mode
libpng already supports eXIf as of v1.6.31.
However, it seems like support was added for normal mode and not added
to push mode.
Notice PNG_READ_eXIfJSUPPORTED is in pngread.c:
https://github.com/pnggroup/libpng/blob/libpng16/pngread.c#L178
but is missing from pngpread.c:
https://github.com/pnggroup/libpng/blob/libpng16/pngpread.c#L274
This commit adds eXIf support to push mode.
