bug: arrays are returned as tuples

[tserg]

Calling foo() returns (1, 2, 3) instead of [1, 2, 3].

@external
def foo() -> uint256[3]:
    return [1, 2, 3]

>>> boa.loads("@external\ndef foo() -> uint256[3]:\n\treturn [1,2,3]\n")

>>> a = boa.loads("@external\ndef foo() -> uint256[3]:\n\treturn [1,2,3]\n")
>>> a.foo()
(1, 2, 3)

What version of eth-abi is this?

I tried with both 3.0.1 and the master branch.
