Update the getLayers method to take in an array of the layer filenames you expect to be in the gerber archive. This will allow the package to be used with gerbers that output different filenames for each layer then EAGLE.
New extractArchive function uses adm-zip instead of node-stream-zip, fixes bug where it wouldn’t wait for all files to be extracted before creating layers.
Replace old getLayers function with the new one that takes in a folder of layers that have already been extracted from a zip archive
