Review comment:
       You are absolutely right about using the TiffTagConstant values in the places you cited.
 Actually, I wanted to make line 244 test for planarConfiguration == "Chunky" rather than
!= "Planar", but I was afraid that there might be places in the code where the planarConfiguration
variable didn't get set correctly.  So I thought this would be safer.
   
   If we ever get our hands on some additional test files, I might revisit this.  But that
may be unlikely...  The Tiff Specification itself describes planar-configuration 2 as follows:
_PlanarConfiguration=2 is not currently in widespread use and it is not recommended for general
interchange. It is used an extension and Baseline TIFF readers are not required to support
it._

> hi,
>  
> we on the OpenJUMP project cannot open some GeoTIFFs with commons.imaging . for details
you may find a ticket in our bug tracker [https://sourceforge.net/p/jump-pilot/bugs/498/] .
>  
> the gist is: on loading the attached file getBufferedImage() fails with this stack
