implement Avail DA

implement Avail as an option for data availability

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
