more_itertools in vendor isn't used?

[oz123]

I am not sure about this, but it seems that this vendord package isn't really used.
Some code was borrowed in the vendord vistir. I don't see it imported anywhere.

Can this be removed?

Playing Indiana Jones here:

more_itertools was added in: b5892c1 together with zipp version 0.6.0. This version used more itertools.

However, zipp removed `more_itertools in version 1.1.0.

Hence, yes. This vendord packages can be removed.
