FS#603 - Support using external LUT

The official drivers come with a file called 'P95D.lut' that consists of a 16-byte header followed by 34 bytes of LUT that neatly fit into the "gamma" header.  I see two approaches:

  1. Add another gamma enumeration, for "external LUT"
    • Have the backend read the file and fil the job at runtime
    • Permanently store the file in the backend, fill job at runtime
  2. Have Gutenprint fill in the gamma table from hardcoded value
  3. Allow gutenprint's gamma table to be overridden.

I'm thinking that pushing this into Gutenprint (hardcoded, but overridable via an option) is the right way to do this.
