openpgp: Make Parse::from_bytes polymorphic over AsRef<[u8]>.

  - A drawback of this change is that currently AsRef<[u8]> is not
    implemented for [u8; _], only for specific lengths.  This is a
    compiler limitation that may be lifted in the future.  This
    limitation required fixing some tests, notably those using
    include_bytes!.

  - Fixes #296.
