StateChanges is missing from provider read SC

[pivilartisant]

Read on provider & sc should have the following (more complete) return type ReadOnlyCallResult

Currently read returns ReadScData which is some times incomplete when making a read

Example:
here I want to access ledger changes after a "purge" call

async function handlePurge() {
    try {
      SC?.read("purge").then((res) => {
        console.log(res);
      });
    } catch (e) {
      console.error("Error while trying to read SC", e);
    }
  }

I get the ReadOnlyCallResult object as a response but it is not accessible due to the resbeing of type ReadSCData
