Switch up Cow Format to be resumable
This switches up the format to alternate ops with data, followed by a
footer containing additional meta information. This allows the file to
be resumed at arbitrary points if writing gets interrupted by power
loss.
Also adds a label op, which allows labeling future ops as connected.
If the footer is missing, Append will treat the last label as possibly
corrupt, and ignore it.
