The package paths were changed. Therefore, go mod tidy
on master failed with:
```
go: finding module for package github.com/hmhealey/go-opengraph/opengraph
go: found github.com/hmhealey/go-opengraph/opengraph in github.com/hmhealey/go-opengraph v0.0.0-20201209151214-f2d823730dba
go: github.com/hmhealey/go-opengraph@v0.0.0-20201209151214-f2d823730dba used for two different module paths (github.com/dyatlov/go-opengraph and github.com/hmhealey/go-opengraph)
