Support unnamed inputs in get_abi_input_names

[reedsa]

What happened?

When I pass an ABI function or event with unnamed inputs, get_abi_input_names throws an error KeyError: 'name'.

According to this article, names are optional.

Code that produced the error

function_abi = {"type": "uint256"}
get_abi_input_names(function_abi)

Full error output

KeyError: 'name'

Fill this section in if you know how this could or should be fixed

return [
arg.get("name", None)
for arg in cast(Sequence[ABIComponent], abi_element.get("inputs", []))
]
