Description

Problem

No issue.

Summary

While debugging #9270 with nargo interpret it was hard to remember which values were correct or incorrect by looking at numbers. With this PR byte arrays that are likely strings will be shown as such, like we do everywhere else when it comes to SSA. For example:

--- Interpreter result after Initial SSA:
Ok(rc3 [rc1 [rc2 b"EN"], rc2 [rc2 b"EN"]])
