Lovell Fuller e6bfa52b0b Add raw pixel data support to boolean and withOverlay ops
The previously-scattered image opening logic has been refactored to a
single ImageDescriptor struct/Object available to both JS and C++ code

This removed about 150 LOC but more importantly reduces the complexity
of adding/exposing new operations that require an input image.
