feat: store blocks by multihash instead of CID (#3124)

Updates the `ipfs-repo` dep to a version that stores blocks by multihash instead of CID to support CIDv1 and CIDv0 access to the same block.

New features:

- Adds a `--multihash` argument to the cli command `ipfs refs local` which prints the base32 encoded multihash of each block

BREAKING CHANGES:

- `ipfs.refs.local` now returns a v1 CID with the raw codec for every block and not the original CID by which it was added to the blockstore

 > Output all local references (CIDs of all blocks in the blockstore)
 
+Blocks in the blockstore are stored by multihash and not CID so yielded CIDs are v1 CIDs with the 'raw' codec. These may not match the CID originally used to store a given block, though the multihash contained within the CID will.
