Convert DCT encoded image bytestream to sRGB

It uses the internal Java classes and the Adobe icm to convert CMYK and YCbCr-Alpha - the data is still DCT encoded.

The Sun class JPEGDecodeParam.java is worth examining because it contains lots of interesting comments

I tried just using the new IOImage.read() but on type 3 images, all my clipping code stopped working so I am still using 1.3
