Thie CAR format used for repository exports is compatible with IPLD. This means
the generic `ipfs` command-line tool (aka,
[kubo](https://docs.ipfs.tech/reference/kubo/cli/#ipfs-dag)) can be used to
import and explore the tree contents.

NOTE: The nested '/' on CID references in the `ipfs dag get` output below seems
to be a representation of the CBOR "tag" for CID types. There is not actually a
nested map/object with a key "/".  This is confirmed by inspecting the raw CBOR
using a python CBOR library (later on below).

Can also fetch raw MST nodes and records:

    # app.bsky.post/3jg4f3m6xas2a record
    $ ipfs block stat bafyreicaxix5adqs6e2yjmp4hui2ugfrn2ahquzrcdzb4b6j5l4xskansa

    Size: 11

    # app.bsky.post/3jg4f3m6xas2a record
    $ ipfs block get bafyreicaxix5adqs6e2yjmp4hui2ugfrn2ahquzrcdzb4b6j5l4xskansa > post.cbor

    # MST node
    $ ipfs block get bafyreidrm6a2yucvumvug253af5fuxxwatgzid2wlq5c23kn5fvztwlbxi > mst_node.cbor

Load CBOR records in python (`python3-cbor`):

    import cbor

    cbor.load(open("./post.cbor", "rb"))
    # {'text': 'blah'}

    cbor.load(open("./mst_node.cbor", "rb"))
    #{'e': [{'k': 'app.bsky.follow/3jg4dmbn5y22a',
