Summary: Enhancement request : specify Tiff Deflate compression level[PATCH] Enhancement request : specify Tiff Deflate compression level

Patch provided adding this feature. The only point I'm unsure is the name of the creation-option. I've chosen 'ZLEVEL'. I find ZIPQUALITY a bit confusing (it's a lossless compression).
