Always close ImageIO reader to prevent memory leaks #82
We were very unhygeniec with our ImageIO readers, never calling .dispose(). This is usually not a problem with pure-Java ImageIO backends, but with the OpenJp2 plugin from imageio-jnr, the reader held a reference to some off-heap memory (~1MiB per reader) that would be leaked without a call to dispose().
