URL for tgz specified in README no longer works

This

https://github.com/pantherdb/TreeGrafter#data-dependencies

says:

```bash
wget  ftp://ftp.pantherdb.org/downloads/TreeMethod/treeGrafter1.01_supplemental.tar.gz
```

But this URL no longer works - should it be replaced by the treeGrafter1.01.tar.gz file here?
