wireproto: define attr-based classes for representing frames

When frames only had 3 attributes, it was reasonable to
represent them as a tuple. With them growing more attributes,
it will be easier to pass them around as a more formal type.
So let's define attr-based classes to represent frame headers and
full frames.
