Issue with image decoding

[gytis-ivaskevicius]

When decoding some of the NIST files it crashes with exception as such:

java.lang.RuntimeException: ERROR : getCMarkerWSQ : No SOI marker : 0
	at org.jnbis.internal.WsqDecoder.getCMarkerWSQ(WsqDecoder.java:85)
	at org.jnbis.internal.WsqDecoder.decode(WsqDecoder.java:19)
	at org.jnbis.api.handler.WsqHandler.decode(WsqHandler.java:71)
	...

Flow is something along the lines of this:

for (VariableResolutionLatentImage fingerprintImage : nist.getVariableResLatentImages()) {
      var xyz = Jnbis.wsq()
           .decode(fingerprintImage.getImageData())  // Throws an exception
           .toJpg()
           .asByteArray();
}

This viewer seems to be able to parse them just fine, not sure if it helps but it says Record Type 13 next to the image

Tested with versions 2.1.2 and 1.2.1

A bit late, but this is probably because some of your .nist files are not compressed with WSQ. (maybe JP2?) I thing the library does not support JP2 compressed files. Correct me if I'm wrong.

might be the case, i dont remember how I ended up working around it and I'm no longer working on that project thus I'm I'm closing this issue
