CI/CD: Configure build process to test and auto-deploy on updates to master

[atla5]

Background

• current set-up does not include tests and requires manually running the deploy command and uploading the resulting files to amazon s3

Success Criteria

• third party CI system is used to run tests on the repository upon creation of a PR
• process for uploading the deployed static app to s3 is automated
• this new process is triggered upon a successful merge into master

note: this only really involves uploading to an s3 folder right now.
