op-challenger: Add script to perform moves.

Update visualize script to use cast to list claims so it works with cannon games.

op-challenger/scripts/move.sh

+#!/bin/bash
+set -euo pipefail

+RPC=${1:?Must specify RPC URL}
+GAME_ADDR=${2:?Must specify game address}
+ACTION=${3:?Must specify attack or defend}
+CLAIM=${4:?Must specify claim hash}
+SIGNER_ARGS="${@:5}"

+# Respond to the last claim that was made
+CLAIM_IDX=$(cast call --rpc-url "${RPC}" "${GAME_ADDR}" 'claimDataLen() returns(uint256)')
+((CLAIM_IDX=CLAIM_IDX-1))
+
+cast send --rpc-url "${RPC}" ${SIGNER_ARGS} "${GAME_ADDR}" "$ACTION(uint256,bytes32)" "${CLAIM_IDX}" "${CLAIM}"
