Chainlink Proof of Reserves composite adapter

This composite adapter first queries a list of custodial contracts of a protocol, then queries the BTC or ETH balances of each of these addresses, and finally reduces the balances to one total result.

At least one of each of the following categories must be set as an environment variable:
