Pull Request Details 📖

We after merging this, we should

• Yank 0.12.2
• Publish 0.13.0

because of the bump of esp-println, and the fact it has a links key now users can end up with two versions of esp-println in their program without choosing to upgrade esp-backtrace (i.e cargo will auto update users to 0.12.2)
