feat(recover): introduce a new command "recover" to recover soft-removed components

[davidfirst]

This new command works regardless of the state in the workspace, specifically tested on the following use-cases:

1. a component was just soft-removed, it wasn't snapped yet, so it's now in .bitmap with the "removed" aspect entry.
2. soft-removed and then snapped. It's not in .bitmap now.
3. soft-removed, snapped, exported. it's not in .bitmap now.
4. a soft-removed components was imported, so it's now in .bitmap without the "removed" aspect entry.
5. workspace is empty. the soft-removed component is on the remote.
