Update the go.mod file to version 1.16, to allow the retract syntax.
~Requires #195 (or equivalent) to be merged first.~
In addition to this, I think we should move this release into a separate branch, revert the changes from master, and cut a v0.6.6 as a successor to v0.6.4 so that we can still have a viable mainline for bug fixes and such.
