Subject: [PATCH] Drop external atomic dependency (#72)

Now that this package only supports Go 1.19 and 1.20,
it can make use of the atomic.Bool [1] added in Go 1.19.

  [1] https://pkg.go.dev/sync/atomic#Bool

This has the effect of eliminating any external dependencies
from this package -- minus testify, which is only used for testing.
