This unpacks new-style packed keys. For now, it can also handle old-style packed keys by passing them to the old unpacking function. Once we've switched over to new-style keys in the signing scripts, we'll remove the old format to save code size. Also added is a test library which converts from old to new struct formats. That should eventually get absorbed into futility, and the test keys directory should have both old and new format packed keys in it.
