Cache the cid

[Stebalien]

go-ipfs and friends make no attempt to cache Node CIDs and will call Cid() repeatedly as-needed. Therefore, calling Cid() should not recompute the CID each time. Instead, it should either be cached on when first computed (preferably, when the node is first decoded).

Furthermore, the raw data should be kept around if possible so that calling RawData() is free. I don't expect this to tie up that much memory.

You can have different CID implementations for different performance use cases, just in case it does tie up too much memory

Different CID implementations? A node's CID should never change (and CIDs are concrete types...).

Ah right
