Check chunk ordering around IDATs

[Oondanomala]

Check for chunk ordering around IDAT chunks, as some chunks have to appear before it (and one has to appear after). See the specification (and the extension).

Also replaces new HashSet<>(Arrays.asList()) with Set.of(), which is nicer looking (and should be slightly faster).

Depends on #6 (mostly because I'm lazy :p)

Fixes most failures on ImageTestSuite.
