v0.3: Huffle Puffer
Third release of the synchronisation server for the third demo of
Revault.
Features:
- We don't return an error anymore on receiving a duplicate
signature
- Newly added fuzzing coverage allows for higher QA
Fixes:
- We now check the database version at startup
- We now replace the signature when being presented a duplicate
(we would previously store both, but it was not reachable
since we would error before)
