fix: ipfs get with raw blocks (#3683)

- tweak ipfs-cli get to handle `raw`
- tweak ipfs-core mapFile to handle `raw`
- mapFile doesn't handle all mapping object or identity types to an IPFSEntry, so throw if it finds one. This makes the cli behaviour match go-ipfs for ipfs get <cbor cid>
- add interface-core test for get with rawLeaves: true
- remove cli test for "raw" as core normalises the type to "file" so it was not testing a valid conditon

fixes #3682
