bug(indexer): inscriptions on inputs after the first are not indexed

[hoale58-vl]

The indexer only record the inscription inscribed on the first input. In my case, I was using batch inscriptions to create multiple inscriptions in one transaction, but only the first inscription was recorded in indexer.

Here is my transaction on testnet:
https://mempool.space/testnet/tx/40c71f4ed13b4587ba3831069edaa69e639e2b7d4ec5ec7ddc22a876c0d478e2

Here is the transaction on your explorer:

You can also check the inscription information on this link:

I have checked your source code. Look like there isn't defination for POINTER_TAG in your inscription envelop. Do you guys have any plan to support this feature?
