d517041044 fix testsuite 
the reencoded length check was supposed to stay commented out,
checking against the original file is too simple and not always correct.

1cb3d225e5 spng_decode_scanline(): rename variable 
make it clear a separate variable is used and ret isn't set to zero,
that would cause an infinite loop.

fc661a8df0 test: change input file for example_notext 
Interlaced, >8-bit images are causing false
positives with MSan, the previous image
 was 1-bit 32x32, it has no trailing padding bits
 when decoded.

eafc9a55c8 decode: keep tRNS high bits when parsing 
masking off high bits is only necessary for
transparency testing, it should otherwise
be stored unmodified.

c43d61107e spng_set_trns(): preserve high bits, refactor

e2f1663336 FILE* / stream write support, new context flag 
SPNG_CTX_ENCODER is a necessity internally,
it should also make user code more readable.
Not sure if SPNG_ENCODE_FINALIZE will ship
in v0.7.0 but it does mirror the decoder's behavior
and libpng.
