We want to make sure that this library is hardened against "extra inputs" during deserialization, where the data provided is longer than strictly required for the deserialization.

An example (that currently fails) with ssz.sedes.Bitlist:

Bitlist(2).deserialize(b'\x07\x00\x00\x00')  # => (True, True)

when the 3 extra \x00 bytes should raise an exception.

The current behavior is to simply ignore them.
