Alt DA layers addition

[apoorvsadana]

Ethereum 4844 DA support should be added with this PR - #7. Adding new DA layers should be very similar to this approach. The steps would be

1. Create a new crate inside da_clients
2. Implement the DaClient trait from da-client-interface
   • publish_state_diff: push the data on chain and return the txn_hash
   • verify_inclusion: taking the txn_hash as input, check if the txn has been finalized on chain

Hi, I would like to take it

Hey, which DA layer would you like to add @Tranduy1dol?

[Tranduy1dol]

Hi @apoorvsadana, I would like to add Aptos as the DA layer. Besides, I'm investigating Avail and Celestia.

The sounds great @Tranduy1dol, can you create an issue for integrating Aptos DA and I can assign it to you!
