Add PNGReadWriterTest>>testNewFromSampleBytes based on a problem report by Hilaire Fernandes, and affecting Dr Geo. The test fails on 64 bit Spur if a synthesized LargeInteger parameter to Bitmap #at:put: is not normalized prior to calling the primitive.

Problem reported at http://lists.pharo.org/pipermail/pharo-users_lists.pharo.org/2017-June/032660.html

No good reason at all, I just copied it verbatim from Hilaire's problem report
on a Pharo mailing list, and I did not think of it.
