Confirm a swap before continuing
**Describe the bug**
When performing a swap, there's no interaction in the cli to confirm the amount, the price, etc thats about to be swapped.
Instead it continues with the swap immediately after executing `swap buy-xmr ...`.

This has caused me to attempt to buy with a seller, and saw the price was absolutely horrible and so I had to cancel quickly with CTRL C. This left my bitcoin to be locked, and it's yet to be determined if I'll have it refunded or not.

**Lost/trapped Funds**
Need to wait 11 hours first as indicated by the GUI

**Platform (please complete the following information):**

- CLI or ASB: CLI
- Software Version: 0.12.3
- Operating System: MacOS
