DAG API example is wrong

[richardschneider]

The dag.put example in https://github.com/ipfs/interface-ipfs-core/blob/master/SPEC/DAG.md is wrong.

const obj = { simple: 'object' }
ipfs.dag.put(obj, { format: 'dag-cbor', hashAlg: 'sha3-512' }, (err, cid) => {
    console.log(cid.toBaseEncodedString())
   // zdpuAzE1oAAMpsfdoexcJv6PmL9UhE8nddUYGU32R98tzV5fv
})

The expected cid of zdpuAzE1oAAMpsfdoexcJv6PmL9UhE8nddUYGU32R98tzV5fv decodes as base58btc cidv1 dag-cbor sha2-256 Qmc9E2LoddF1MdSVzYaaFxr6iByWSa2Q7pSpiKHcV4drm6.

The hash algorithm should be sha3-512 not sha2-256.

This is related to ipld/js-ipld#82

@PascalPrecht any chance you can send a PR to fix this up? 😉 🙏

On my way!

The hash algorithm should be sha3-512 not sha2-256.

Well actually, the algorithm is right, but the hash should be different. I guess the example should demonstrate how to override the default hash algorithm (which is already sha-256). I'll send a PR to update the hash
