add handler for tuple

[Almenon]

add the handler to https://github.com/Almenon/AREPL-backend/blob/master/python/arepl_custom_handlers.py

from collections import namedtuple
Person = namedtuple('Person', 'first_name last_name zip_code')
p1 = Person('Joe', 'Schmoe', '93002')
print(dir(p1))
print(p1.__repr__)

Named tuples are not represented well in the variable viewer - the important part of the tuple is the py/seq and py/newargs isn't really necessary.

vars:

-{
    Person: -{
        py/type: "__main__.Person"
    },
    p1: -{
        py/object: "__main__.Person",
        py/newargs: -{
            py/tuple: +[3 items]
        },
        py/seq: -[
            "Joe",
            "Schmoe",
            "93002"
        ]
    }
}
