Allow use sha256 in TLC.

See contract PR nervosnetwork/fiber-scripts#6

  • Added a field hash_algorithm when adding TLC
  • Save the hash_algorithm in the internal TLC struct
  • Check hash against preimage using the saved hash_algorithm
  • Added hash_algorithm in the invoice as a new attribute

The sha256 TLC is covered in the e2e test case 3-nodes-transfer with extra args --env-var HASH_ALGORITHM=sha256

Generally LGTM. We may also need to update the binaries in the folder tests/deploy/contracts so that we can use the latest contracts. There are some tests in this repo that directly run these contract to see if the generated transactions are valid.
