Add diagnostic for panic/todo in option.unwrap / result.unwrap

[u9g]

The suggested fix should be maybe_x |> option.lazy_unwrap(fn () { panic }) which is likely what the user wanted, as using maybe_x |> option.unwrap(panic) always panics since the argument isn't lazily evaluated. todo has the same problem as panic here.
