I noticed that the pion-ice package had ~1MB of extra binary size due
to the dependency on stretchr/testify.
Renaming test_utils.go to utils_test.go removes stretchr/testify from
any non-test build and fixes this dependency. The tests still pass and
the package still builds the same.
One can check the dependency graph with goda:
