Option to record only failing snapshots

[Scvairy]

Now, when I need to regenerate changed snapshots, I regenerate all of them and have a massive diff in VCS (because newly created snapshots have different metadata?)
I'd like to minimize unnessecary snapshots (equal with the previous reference) being commited

Can I do that?

We suppose this already with Record.failed. Pass that to withSnapshotTesting to configure the record mode.
