Goal

For ShareExchange and DASing to work we need to use IPLD implementation of NMT, which is currently located in Core. The Node needs to use it as well, so we need to extract the plugin with supporting functions into a separate repo to be used by both Core and Node repos.

Actions

• Create new repo ipld: move IPLD plugin into separate repo #111
• Cherry-pick plugin and ipld package from Preliminary introduction of RowSet with supporting changes celestia-core#427
• Define what logic should be in the repo and what should be part of Node repo.
• Update core and close ipld: consider moving into separate repo celestia-core#296
• ipld: Consolidate parameters used for square size. #114
