• fix op-node/rollup/finality/plasma_test.go. uncomment the failed test

• feat: update tryFinalize() to check finality on each L2 block babylonchain/optimism#23 (comment): we should have a test case for this where fd.L1Block is different from lastFinalizedBlock.L1Origin

• feat: update tryFinalize() to check finality on each L2 block babylonchain/optimism#23 (comment): we shouldn't keep iterating if some blocks in the range is not finalized. see if we should add a test case

• design and implement more tests in finalizer_test.go
