Show valid parameters of invalid CIDs instead of just an error

[Winterhuman]

If you modify https://cid.ipfs.io/#bafk2bzaceaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa to be one character shorter than it should be, all the information disappears save for the multihash length inconsistent: error even though the valid multibase, multicodec, etc, are still present. It'd be nice if only certain sections were omitted when invalid parameters were present.
