Add CI/CD Workflows & remove Travis.

Details

Travis removal

We previously removed our Travis workflow but have yet to remove some lingering artifacts. In addition to testing, we used Travis to trigger a production build that uploaded the SDK files. With Travis gone, we need to replace the functionality:

• Remove Travis config file
• Remove references to Travis from docs

Github Actions

Tests will now run automatically upon pull request creation in Github Actions. Our CD pipeline will be triggered manually.

• Add ci.yml and cd.yml
