Title: (feat) Handler unsafe.

- Prepares `Furnace` for `Iron` integration
- Adds `from_furnace`, `new`
- Adds `iron.smelt`
- Documents new methods on `Furnace`
- Implements defaults for `IronFurnace`
- Implements `handle_request` (unsafely, to `transmute` the `ResponseWriter` to trait type (`Rs`)

This can be broken into two PRs if that is preferable (`furnace` and `handle_request`), but the latter depends on the former, so we would need to chain them either way.
