Vechain(VET) Network Upgrade & Hard Fork

This release will activate the hardfork named FINALITY on MAINNET. It implements the VIP-220 Finality with One Bit (FOB) that allows nodes to be able to check the finality of blocks.

All MAINNET nodes are required to be upgraded ASAP.

The hardfork is scheduled at block #13815000 (~ Thu, 17 Nov 2022 08:10:00 GMT) on MAINNET.

New feature: you will be able to query finalized block via curl http://localhost:8669/blocks/finalized

Don't forget that full resynchronization is required if upgrading from versions earlier than v1.7.0.
