We were defer closing the IO for run/exec/start fairly late in the
container run cycle which had the downside of that if the container run
failed your tty would be stuck in raw mode. This change just moves the
closing (return tty to origin state) to directly after we create the IO.
This PR introduces the `Differ` with methods:
```swift
// Differ protocol
func diff(base: Snapshot?, target: Snapshot) async throws -> Descriptor
func apply(descriptor: Descriptor, to base: Snapshot?) async throws -> Snapshot
```
It also introduces `DiffKey`, which is a MerkeTree based key for fast
diff computations between two dirs
0.5.0 introduces a new way to configure the containers and execs. This
is now done all upfront at constructor time in a callback style. I'm
very happy with the config improvements, but because IO can only be
setup at constructor time this makes it so that we need to supply IO at
creation time of the VM or exec, which isn't the end of the world. All
that really changes is `boostrap()` and `createProcess()` now take in IO
instead of slightly later in `process.start()`
Define a `UnpackStrategy` function type in the `SnapshotStore` to give
more control over how an image is unpacked.
Previously, we were creating a 512 GB sparse block file for the initial
file system of a container, which is overkill.
With this change, the vminit image is unpacked to a smaller block file,
while container images are unpacked to the 512 GB block
Follows the same pattern as

See discussion below for example. For multiple network interfaces in a
single container we'll want to integrate against a containerization that
includes apple/containerization#156.
The change bumps the containerization dependency to 0.2.0 and addresses
the breaking API changes.
