Migrate Rollkit adapter to go-da

[Wondertan]

The Rollkit team has been working on the new and better DA abstraction landed at https://github.com/rollkit/go-da. The Sugondat adapter for Rollkit will have to support it soon as Rollkit already migrated.

Example implementation: https://github.com/rollkit/celestia-da/blob/main/celestia.go

We'll update to the new DA abstraction shortly.

Thanks @Wondertan that makes sense! I actually first found go-da but then was confused how to integrate it. After a brief look at the PR I still don't know how to do it. I would appreciate a pointer if you have handy.
