Bugfix: BadZipFile when you get into a weird corrupted state

[cmalinmayor]

Proposed Change

Because we don't re-download the zip if it is already present, if it gets corrupted it will stay corrupted forever. There was clearly something reproducible that was corrupting it in our workflow that is still undiscovered (Killing the process during unzip, maybe?). But, now we catch the exception and re-download the zip, removing the corrupt version.

Closes #31
