lnwire: replace instances of *btcec.PublicKey with [33]byte in ann messages

Browse Source 
In this commit, we replace all instances of *btcec.PublicKey within the
announcement messages with a simple [33]byte. We do this as usually we
don’t need to immediately validate an announcement, therefore we can
avoid the scalar multiplications during decoding.
