v0.7.0-rc.36

Changes since rc.35

• Fixed orphaned channel migration blocking node startup when the existing monitor
  in the KV store can't be deserialized (e.g., UnknownVersion from a newer LDK
  version). The migration now skips writing and lets the node start normally,
  preserving the existing monitor data.
• Switched rust-lightning fork from ovitrif/rust-lightning to synonymdev/rust-lightning#0.2.2-accept-stale-monitors.
