ci: configure codecov upload during PR (#394)

## This PR

- adds codecov to PR runs
- updates make test to include recommended test flags

### Notes

This change includes test flags for `race` and `covermode` based on a
recommendation from
[Codecov](https://about.codecov.io/blog/getting-started-with-code-coverage-for-golang/).
Looking into the flags, they both seem like good ideas and run fine
locally.


### How to test

Run make test locally.
