2d78949365 Speed up mapImage8Bit and mapImageCustomBit (#123) 
Inner loop with `if()` comparison is eliminated and replaced with
function call.

Synthetic benchmark shows 1.5x increase in speed of mapImage8Bit for big
PNG images (e.g. 4064 x 2338, 8-bit/color RGBA, non-interlaced
screenshots).

a0596a58c4 Introduce deflateFactory option to packer 
The main application motivating this addition is the creation of
reproducible compression results.  Since `zlib` is shipped with node.js, we
have no control over its version via npm.  To guarantee reproducible
results, other libraries (like pako) could be used, with a fixed version
number to guarantee consistent behavior.  This modification provides a hook
to allow such usage.
