This restructures and refactors the project to split up the
implementation into smaller fragments. The majority of the operations
are portable: the ones which are not require iterating the heap
allocations which is not guaranteed to be a portable operation.
Additionally, the `Inspector` class is renamed into `RemoteProcess`
which is also converted to a protocol to allow adding in an
implementation for other targets. The inspection operations are split
off into individual files to make it easier to follow. Take the
opportunity to use `@main` for the entry point.
