Is your feature request related to a problem? Please describe.
A new pattern named single use lock(https://talk.nervos.org/t/en-cn-misc-single-use-seals/8279/2), which is inspired by RGB++, was introduced on CKB.

They are now deployed on

# mainnet
    {
      "name": "single-use-lock",
      "tx_hash": "0x10d63a996157d32c01078058000052674ca58d15f921bec7f1dcdac2160eb66b",
      "index": 4,
      "occupied_capacity": 2783700000000,
      "data_hash": "0x8290467a512e5b9a6b816469b0edabba1f4ac474e28ffdd604c2a7c76446bbaf",
      "type_id": null,
      "hash_type": "data1"
    }
# testnet
    {
      "name": "single-use-lock",
      "tx_hash": "0xb4f171c9c9caf7401f54a8e56225ae21d95032150a87a4678eac3f66a3137b93",
      "index": 4,
      "occupied_capacity": 2783700000000,
      "data_hash": "0x8290467a512e5b9a6b816469b0edabba1f4ac474e28ffdd604c2a7c76446bbaf",
      "type_id": null,
      "hash_type": "data1"
    }

The source code can be found at https://github.com/ckb-ecofund/ckb-proxy-locks

When an xUDT was issued by a single-use-lock, the token cannot be minted more because the owner is ephemeral, works as xUDT issued by an RGB++ Lock.

On-chain cases:

Mainnet: https://explorer.nervos.org/xudt/0x27ab2471d79c4953a614a7d60d0ad1d376e8110a6ac6046f4bd6b012533bdf2d
Testnet: https://pudge.explorer.nervos.org/xudt/0xcef135ddca02a931e5b21235fe42f81fe93b01a2161699db4b3a1ae0ac795ec8

Describe the solution you'd like

  1. Mark as limited supply when a token(xudt, xudt-compatible, inscription, dob/spore) is issued with single-uselock`
  2. Mark single-use-lock in script info
