lnwire: all hashes within the protocol are now 32-bytes
We now enforce that the site of all revocation pre-images+hashes (used
for HTLC’s) are now 32-bytes.

Additionally, all payment pre-images are now required to be 32-bytes
not he wire. There also exists a Script level enforcement of the
payment pre-image size at a lower level.

This commit serves to unify the sizes of all hashes/pre-images across
the codebase.
