Resolve the packing size issue

• Remove the C source code from npm package to reduce to package size from 200 MB to 10 MB
• Store the source code in S3 and user can configure it from env variable for the host
• Only download the source code if no binary find and delete it once finishes local build to reduce the size

NOTE: This version is mostly for testing, will bump up the major version once we test thoroughly.
