[eth] Add Canto mainnet (#751)

* [eth] Add Canto mainnet

This deployment also enables contract rewards on canto. Since the
changed code is only specific to the Canto network and is used only
in initialization, only the diff is added as a file.

* Remove ds store

* Add some doc to deploying.md

+# Deploy/Upgrade on Canto
+
+Canto network rewards some percentage of the gas usage to the contracts. To enable the rewards we have modified the contract upon
+deployment to register its own address as the receiver of the rewards and also assigned Pyth to received Wormhole Receiver rewards
+too. The registration only happens once for contract. The contracts are registered with token id 654. We don't need to register
+the contracts upon upgrades because the proxy address doesn't change. The contract changes for registration are stored in
+[this diff](./canto-deployment-patch.diff) for future reference. Please note that if we switch to another Wormhole Receiver
+(a new address) we will need to register the new contract.
