Build and deploy tools of Verpix Viewer

[SuJiaKuan]

Add automation tools for building and deploying, include:

• Compress the output JS files by gzip
• Deploy the output files onto AWS S3
  • Upload output files to S3 automatically
  • S3 permission settings for all files: public
  • S3 metadata settings for js files:
    • Cache-Control: max-age=600
    • Content-Encoding: gzip

The compression issue is resolved (TopPano/verpix-viewer#5) by gzip output JS files in Webpack.

does the issue need to be closed?

@uniray7 I will close the issue after S3 uploading in CI/CD prototype is finished.
