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.
