Retarget submodule.

I think this should work? I'm not sure why the changes I made to `.gitmodues` are not showing as well. 

Contents of `.gitmodules` should be:

```
[submodule "telescope_control/PyGalil"]
	path = telescope_control/PyGalil
	url = https://github.com/fake-name/PyGalil
	branch = master
```
