Adjustable CID parameters

https://cid.ipfs.io/#bafk2bzaceaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa tells the user about the CID, however, it'd be nice if some of the parameters were dropdowns so you could see what the CID looks like if slightly changed.

e.g. Changing `Name: base32` to `Name: base36` with a dropdown menu that shows all multibases available. This is especially useful since some encodings mean the characters don't neatly align to a single, whole byte each.

It might also be of benefit to give the user the option to manually type in multiformat codes to see how non-standard multiformats would be encoded.
