useContractCall is getting replaced by useCall​

It is being replaced with useCall that supports typed contracts from type-chain.

Before:

const [tokenBalance] =
  useContractCall({
    abi: ERC20Interface,
    address: tokenAddress,
    method: 'balanceOf',
    args: [address],
  }) ?? []

After:

const { value: tokenBalance } =
  useCall({
    contract: new Contract(tokenAddress, ERC20Interface),
    method: 'balanceOf',
    args: [address],
  }) ?? {}

useChainCall is getting replaced by useRawCall​

useRawCall returns an object in the form of { value, error } for each calls. This allows to get individual errors for each failing call.
