get inputs from signature instead of decorator

All of the changes are really in coroutine.py. I tried to adopt the same style of using type hints like magma, but it ended up with a bunch of function calls expecting those arguments to be passed into the coroutine when constructing the circuit so I captured them in the coroutine decorator and instantiate the function with arguments.

@leonardt you might know a better way to go about handling this?
