Add a test for decoding a gif with sampleSize 4.
Prior to https://codereview.chromium.org/1085253002/, this would crash.
Only happens with interlaced gif images with an odd height. (Maybe
there are more restrictions?)
Test image provided by zoran.jovanovic@sonymobile.com for checking in.
Add include before includes.
