Upgrade to latest ipld-dag-cbor #1610
Description
We made a pretty big change to the ipld-dag-cbor API.
Instead of using {"/": baseEncodedString} to express links we're just using CID instances.
This will probably end up simplifying a bunch of code in js-ipfs but it will be a pretty impactful change. For encoding, we still support the old form, so you only need to move to the new way once you find it necessary. But, there's a breaking change on the decoder side because all links are now CID instances.
The direct ipld-dag-cbor dep is barely used, it's mostly used by deps of deps:
├─┬ interface-ipfs-core@0.78.0
│ └── ipld-dag-cbor@0.12.1
├─┬ ipfs-api@24.0.2
│ └── ipld-dag-cbor@0.12.1
├─┬ ipfsd-ctl@0.39.2
│ └─┬ ipfs-api@23.0.0
│ └── ipld-dag-cbor@0.12.1
├─┬ ipld@0.17.3
│ └── ipld-dag-cbor@0.12.1
└── ipld-dag-cbor@0.21.1
What's the best strategy for getting all the deps of the deps updated and into a release?
We don't want to release "ProtoSchool 1.0" until this changes is in a js-ipfs release. Link creation w/ ipfs.dag.put in IPFS is a big part of the basic tutorials and the new API is much nicer and easier to teach and we'd hate to teach people the old API and then change it a month later. But this also means that this dep upgrade will end up being a blocker for ProtoSchool if it lingers for too long.
