Avoid UB with setjmp() in getimage_libpng() (#185) 
The pointers may get modified between the setjmp() call
and any later longjmp(), therefore they should be declared volatile.

Fixes #183.

decode: allow setting of image window bits (#181) 
This shouldn't change any defaults but allow for a smaller inflate window size
with spng_set_option(ctx, SPNG_IMG_WINDOW_BITS, 0),
zlib will pick a smaller window size if the zlib header indicates a smaller-than-default size.
Malformed headers do exist where the actual size is bigger than indicated and
would lead to a decode error, it cannot be made the default behavior.
