Specify build directory

[joshbrown]

Thank you so much for this - I've been looking for a way to build NodeJS layers easily.

Is there already a way to specify an output directory for the zipped file?

I noticed there is the SUBDIR_MODE in build.sh, but don't really understand how it's used.

What are your thoughts on adding a -o OUTPUT_DIR to the build script?

Well, easiest solution would be just to add a move command after the zip file is created to the build.sh
