69d88505fd go mod: declare module version v2
translated all instances of "github.com/rfjakob/gocryptfs/" to
"github.com/rfjakob/gocryptfs/v2/".
Unfortunately, this included hyperlinks.
Unbreak the hyperlinks like this:
find . -name \*.go | xargs sed -i s%https://github.com/rfjakob/gocryptfs/v2/%https://github.com/rfjakob/gocryptfs/v2/%
