Got empty children from 16bit psd

[599316527]

psd.js/lib/psd/layer_mask.coffee

Lines 38 to 42 in 333dd14

	parseLayers: ->
	layerInfoSize = Util.pad2 @file.readInt()
	if layerInfoSize > 0
	layerCount = @file.readShort()

this.file.pos of reading layerInfoSize is wrong when the psd image mode is in "16bit/channel". I found pos is offseted by the length of image resource section correctly but somehow there are still 8 bytes of zero and "8BIMLr16" before layerInfoSize. According to Adobe's document，it makes no sense.

With extra offsets of 12, layerInfoSize is read correctly. It works to me.

layerInfoSize = Util.pad2(this.file.readInt());
if (layerInfoSize === 0 && this.header.depth === 16 
    && this.file.data.slice(this.file.pos + 4, this.file.pos + 12)
             .compare(Buffer.from('8BIMLr16')) === 0) {
  this.file.pos += 12;
  layerInfoSize = Util.pad2(this.file.readInt());
}
if (layerInfoSize > 0) {

Seems to be duplicate of #105

Also you can write in coffescript for 16 or 32 bits :

 if layerInfoSize is 0 and (@header.depth is 16 or @header.depth is 32)
        @file.pos = @file.pos + 12
        layerInfoSize = Util.pad2 @file.readInt()

But when I parse on 16 or 32 bits psd I get an error from channel_image.coffee file where parseZip is undefined #174

Seems like good fix? #175
