obsstore: refactor v1 logic to fix 32 byte hash support

Refactor the v1 logic to determine the node parsing based on the flag.
Move the predecessor out of the fixed part and handle it like the other
nodes, removing most of the duplicated code for parsing 20/32 bytes
hashes.

Check data can be written/read from sidedata

Check upgrade behavior
======================

Right now, sidedata has not upgrade support

Check that we can upgrade to sidedata
