Add project badges to README

[darylwright]

Add badges to the README.md to better communicate the status and type of project, and also stats such as code coverage percentages. There is also a badge that communicates that a project uses conventional commits. Some ideas below for badges:

• code coverage
• license
• conventional commits
• build status
• latest release
• code of conduct?
• sponsorship?
• crypto (https://en.cryptobadges.io/)

Use https://shields.io/ to generate badges that don't have an existing template somewhere.

Good example projects for badges and README formats:
