Fix compression

After extensive testing it was determined that under all circumstances

Deflater def = new Deflater();
def.setLevel(Deflater.BEST_SPEED);

results in no compression. The input data does not matter, nor does the level being set, providing it is different to the existing level. However,

Deflater def = new Deflater(Deflater.BEST_SPEED);

always works with no issues. Updated the code to reflect this.
