Axelar Router

This AxRouter contract extends the Router contract functionality plugging in the Axelar network to send and receive arbitrary cross-chain payloads. It extends the router to:

1. Map a standardised chainId to Axelar chain name as string

2. Set the Axelar-powered peer router address on each remote chain

3. Receive incoming messages and dispatch them to the correct smart contract.
