Fix go modules

The last release (v2.1.1) was created to add the go.mod file. Given that this repository is already beyond v2 release-wise, and importers are already using the "v2" version of this package at a technically-v1 path, this is the lowest-impact way of un-breaking go modules. This release is simply to set this repository back to "not using Go modules" territory.

See #24 for further discussion and details.
