func ChunkifyHash

func ChunkifyHash(wareID api.WareID) (string, string, string)

Return a first, second, and remaining chunk of a ware's hash as strings.

These are the first three, second three, and remaining bytes of the string. For base58 encoded values, these first two chunks used as dir prefixes are a cozy density for storing many many thousands of objects:

If the hash is too short, we return a bunch of dashes. (The hash is probably invalid semantically anyway, but we're not going to error about that here.) A hash of empty string will result in a return of `"---", "---", "-"` (in other words, as if the hash had been padded to a min of 7 characts, all dashes).
