It would be nice to add Less()

[aboodman]

It's common to want to sort Cid, which requires an implementation of Less(). This can be done more efficiently inside Cid than outside because it won't require allocation if done inside (can directly access member fields which aren't exposed outside the package).

@Stebalien any thoughts here?

[Stebalien]

We're switching to string-backed CIDs so KeyString() will no longer allocate (today?). Once we do that, we can merge: ipfs/go-cidutil#5

We are now using string-backed CIDs.
