Delete bounces

**This endpoint allows you to delete all emails on your bounces list.** There are two options for deleting bounced emails: 1. You can delete all bounced emails by setting `delete_all` to `true` in the request body. 2. You can delete a selection of bounced emails by specifying the email addresses in the `emails` array of the request body. **WARNING:** You can not have both `emails` and `delete_all` set.
