removing typehint outputs

[mfinzi]

Type annotations on outputs of dispatched functions perform type conversion and this functionality is not intended for our usage. (Problems for parametric types are caused because e.g. Kronecker[A,B] doesn't match Kronecker and then plum attempts to perform a type conversion.

@dispatch
def fn(...) -> Kronecker:
