add test for invalid ancillary after IDAT

Similar to the other invalid ancillary test but here, the invalid chunk is after IDAT rather than before it.

The test PNG was created from a copy of the valid reference PNG; I inserted a tRNS chunk in TweakPNG, moved it after IDAT (accepting the warning) and saved. Then in a hex editor I changed "N" (0x4E) to 0x0E, saved, ran it through PNG file chunk inspector to get the new CRC value, and typed that in in a hex editor.

Chunk summary: IHDR, gAMA, PLTE, IDAT, tR␎S, IEND
