--branch is too greedy, causing it to consume positional arguments

[typecasto]

I'm trying to run assigner get --branch main hw1, but I'm getting the following error:

usage: assigner get [-h] [--branch BRANCH [BRANCH ...]] [-f] [--section [SECTION]] [--student id] [--attempts ATTEMPTS] name [path]
assigner get: error: the following arguments are required: name

I suspect this is a result of --branch taking multiple arguments, and being greedy in consuming those arguments, causing it to interpret my command as (assigner) (get) (--branch main hw1) (*missing positional parameter*). I suggest making --branch take a single argument, and allow it to be specified multiple times instead. This would alleviate the ambiguity in parsing positional arguments.

I'm assuming this is true of any argparse with multiple, like commit -a commit -r as well. We can at least note that one should include the assignment name before these, which does work well enough.
